I npm installed everything, yet only web3 is not working? Is this a bug or is there an alternative to this solution?
import React,{useEffect, useState}from 'react';
import { Connection, PublicKey,Account } from '#solana/web3.js';
import { MintLayout, TOKEN_PROGRAM_ID, Token } from '#solana/spl-token';
import { Program, Provider } from '#project-serum/anchor';
import { sendTransactions } from './connection';
import './CandyMachine.css';
Error message below
export 'web3' (imported as 'web3') was not found in '#solana/web3.js' (possible exports: Account, Authorized, BLOCKHASH_CACHE_TIMEOUT_MS, BPF_LOADER_DEPRECATED_PROGRAM_ID, BPF_LOADER_PROGRAM_ID, BpfLoader, Connection, Ed25519Program, Enum, EpochSchedule, FeeCalculatorLayout, Keypair, LAMPORTS_PER_SOL, Loader, Lockup, MAX_SEED_LENGTH, Message, NONCE_ACCOUNT_LENGTH, NonceAccount, PACKET_DATA_SIZE, PublicKey, SOLANA_SCHEMA, STAKE_CONFIG_ID, STAKE_INSTRUCTION_LAYOUTS, SYSTEM_INSTRUCTION_LAYOUTS, SYSVAR_CLOCK_PUBKEY, SYSVAR_EPOCH_SCHEDULE_PUBKEY, SYSVAR_INSTRUCTIONS_PUBKEY, SYSVAR_RECENT_BLOCKHASHES_PUBKEY, SYSVAR_RENT_PUBKEY, SYSVAR_REWARDS_PUBKEY, SYSVAR_SLOT_HASHES_PUBKEY, SYSVAR_SLOT_HISTORY_PUBKEY, SYSVAR_STAKE_HISTORY_PUBKEY, Secp256k1Program, SendTransactionError, StakeAuthorizationLayout, StakeInstruction, StakeProgram, Struct, SystemInstruction, SystemProgram, Transaction, TransactionInstruction, VALIDATOR_INFO_KEY, VOTE_PROGRAM_ID, ValidatorInfo, VoteAccount, VoteAuthorizationLayout, VoteInit, VoteInstruction, VoteProgram, clusterApiUrl, sendAndConfirmRawTransaction, sendAndConfirmTransaction)
actually you dont have to call web3 because you already imported Connection, PublicKey, Account directly.
example:
import { Connection, PublicKey } from '#solana/web3.js';
// Create new connection
const connection = new Connection(
web3.clusterApiUrl('devnet'),
'confirmed',
);
// Generate a new random public key
const somePublicKey = new PublicKey("someBase58AddressXxxXXXx2323")
if you want to call web3, your import should could be look like below:
import * as web3 from '#solana/web3.js';
// Create new connection
const connection = new web3.Connection(
web3.clusterApiUrl('devnet'),
'confirmed',
);
// Generate a new random public key
const somePublicKey = new web3.PublicKey("someBase58AddressXxxXXXx2323")
// etc
Error is clear. #solana/web3.js has no web3 to be exported. If you want to connect
import * as anchor from '#project-serum/anchor';
import { clusterApiUrl } from '#solana/web3.js';
const rpcHost =https://api.devnet.solana.com
const connection = new anchor.web3.Connection(rpcHost
? rpcHost
: anchor.web3.clusterApiUrl('devnet'));
If you are working on VS Code, then after installaing web3 via pip, just restart the VS Code editor. It will then find Web3.
Be careful about below line:
from web3 import Web3 <- Small and Capital 'W'
Again, installing web3 requires Visual Studio Build Tools to be installed

so whenever I want to import a model via GLTFLoader locally I get this error:
JSON.parse: unexpected character at line 1 column 1 of the JSON data
but when I try it via a link it works.
The link I tried with is:
https://s3-us-west-2.amazonaws.com/s.cdpn.io/39255/ladybug.gltf
I tested the models I used in the official three.js-Editor and even exported them from there to get a "clean" gltf model. I also saved the content of the link in a gltf file and it didnt work neither.
This is my code:
import * as THREE from 'three';
import { OrbitControls } from 'three/examples/jsm/controls/OrbitControls.js';
import { GLTFLoader } from 'three/examples/jsm/loaders/GLTFLoader.js';
async function run() {
try {
var loader = new GLTFLoader();
loader.crossOrigin = true;
loader.load(
"./scene.gltf",
//"https://s3-us-west-2.amazonaws.com/s.cdpn.io/39255/ladybug.gltf",
function (data) {
var object = data.scene;
object.position.set(0, 0, 0);
scene.add(object);
}
);
} catch (e) {
console.log(e);
}
}
run();
As Marquizzo said: You have to run a local server for the models. You cannot import them via a path normally, because of security restrictions.
I'm trying to connect to a database using Groovy and can't.
The same error pops up even though i've tried a few things.
The error is "No such property: driver for class".
I known the connection works as i have tried it on the DBeaver app without issues.
The code is as follows:
package com.database
//import java.sql.DriverManager
import java.sql.ResultSet
import com.google.api.client.util.Data
import com.kms.katalon.core.annotation.Keyword
//import com.mysql.jdbc.Connection
//import com.mysql.jdbc.Statement
import groovy.sql.Sql
import java.sql.Driver
import groovy.lang.GroovyClassLoader
import org.codehaus.groovy.tools.RootLoader
import java.sql.Connection
import java.sql.DriverManager
import java.sql.ResultSet
import java.sql.ResultSetMetaData
import java.sql.SQLException
import java.sql.Statement
import groovy.sql.Sql
import com.kms.katalon.core.annotation.Keyword
import groovy.sql.*
public class mySql {
#Keyword
def connectDB(String username, String environment, String url, String port, String dbname, String password){
//* Attempts:
//#GrabConfig(systemClassLoader=true)
//#Grab('mysql:mysql-connector-java:S5.1.27')
// Data Source = MyOracleDB;
//SERVER=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=host)(PORT=port))(CONNECT_DATA=(SERVICE_NAME=MyOracleSID)));uid=username;pwd=password;
// Class.forName(driver);
// Connection con = DriverManager.getConnection(connect, username, password);
// Statement statement = con.createStatement();
String connect = username+"#//srv" +environment + url + ":" + port + "/" + dbname
if(connection != null && !connection.isClosed()){
connection.close()
}
def connection = DriverManager.getConnection(connect, username, password)
return connection
}
If anyone can help would apreciate it.
Thanks in advance.
It is much simpler than your code suggests. You can still build a string for the newInstance(). Not in a class for simplicity in my example.
import groovy.sql.Sql
def myDB = Sql.newInstance('jdbc:mysql://127.0.0.7:3306/employees', 'user1', 'pass1', 'com.mysql.jdbc.Driver')
myDB.eachRow("select first_name, last_name from employees.employees;"){
println "${it.first_name} ${it.last_name}"
}
myDB.close()
I'm working on a custom SPFX commandset. It opens a dialog with an iframe to an 3rth party platform. I'm able to receive a json through a postmessage. From this json, I convert it's data to a file, with it's proper metadata. All of this works like a charm... Except...
Now I want to upload this file to a document library, and it drives me crazy.
I'm referencing:
import "#pnp/polyfill-ie11";
import { ConsoleListener, Logger, LogLevel } from "#pnp/logging";
import { sp } from "#pnp/sp";
import { Web } from "#pnp/sp/webs";
import "#pnp/sp/webs";
import "#pnp/sp/files";
import "#pnp/sp/folders";
import { Base64 } from 'js-base64';
In my dialog component, I try to upload the file with web.getFolderByServerRelativeUrl. But this method is failing, and I really don't understand why.... Looking at the pnp reference (https://pnp.github.io/pnpjs/sp/files/), It seems like the right way.
var file = Base64.atob(response.Data);
console.log("File length : " + file.length);
let web = Web("https://MyTenant.sharepoint.com/sites/Customer"); // this is successful
await web.getFolderByServerRelativeUrl("/sites/Customer/Shared%20Documents/")
.files.add(response.fileName, file, true); // this fails
The context is set on the CommandSet onInit()
#override
public onInit(): Promise<void> {
Log.info(LOG_SOURCE, 'Initialized myCommandSet');
pnpSetup({
spfxContext: this.context
});
return Promise.resolve();
}
Hope you guys and girls can point me in the right direction...
EDIT:
Error:
HTTP400: INVALID REQUEST - The request could not be processed by the server
due to an invalid syntax
POST - https://MyDevTenant.sharepoint.com/sites/customer/
_api/web/getFolderByServerRelativeUrl
('%2Fsites%2Customer%2FShared%2520Documents%2F')
/files/add(overwrite=true,url='')
Is it the url from the documentlibrary that messes things up?
Thanks to Willman for giving me a right direction.
This did the trick:
import { sp, Web, IWeb } from "#pnp/sp/presets/all";
import "#pnp/sp/webs";
import "#pnp/sp/lists";
import "#pnp/sp/files";
import "#pnp/sp/folders";
const web = await sp.web();
const list = sp.web.getList("Documents");
const listId = await list.select("Id")();
await sp.web.lists.getById(listId.Id).rootFolder.files.add(docname, file, true);
I get "Error while updating 'end' in shadow node of type: BVLinearGradient" error when i run my react native app and the error seems to emanate from my MainApplication.java file here is my code:

// No need to add RnnPackage and MainReactPackage
return Arrays.<ReactPackage>asList(

Please help me resolve this
This is a bug with the react-native-linear-gradient. The issue is in open status. For the time being, there are 2 solutions-
Replace start with startPoint and end with endPoint props for <LinearGradient/>
Downgrade react-native version to 0.50.3
The details for this issue is below:

I am trying to set up my project to use the Google Calendar API. So far I have downloaded the latest libraries and imported them. At the moment I am trying to follow the tutorial from the Google developers which is found here.
From what I found out according to this link draft10 has been deprecated and I am trying to use other classes
which do not belong to draft10.
The following are my current imports:
import com.google.api.client.auth.oauth2.Credential;
import com.google.api.client.auth.oauth2.AuthorizationCodeTokenRequest;
import com.google.api.client.extensions.java6.auth.oauth2.AuthorizationCodeInstalledApp;
import com.google.api.client.extensions.jetty.auth.oauth2.LocalServerReceiver;
import com.google.api.client.googleapis.auth.oauth2.GoogleAuthorizationCodeFlow;
import com.google.api.client.googleapis.auth.oauth2.GoogleAuthorizationCodeRequestUrl;
import com.google.api.client.googleapis.auth.oauth2.GoogleAuthorizationCodeTokenRequest;
import com.google.api.client.googleapis.auth.oauth2.GoogleClientSecrets;
import com.google.api.client.googleapis.auth.oauth2.GoogleTokenResponse;
import com.google.api.client.googleapis.batch.BatchRequest;
import com.google.api.client.googleapis.batch.json.JsonBatchCallback;
import com.google.api.client.googleapis.javanet.GoogleNetHttpTransport;
import com.google.api.client.googleapis.json.GoogleJsonError;
import com.google.api.client.http.HttpHeaders;
import com.google.api.client.http.HttpTransport;
import com.google.api.client.http.javanet.NetHttpTransport;
import com.google.api.client.json.JsonFactory;
import com.google.api.client.json.jackson2.JacksonFactory;
import com.google.api.client.util.DateTime;
import com.google.api.client.util.Lists;
import com.google.api.client.util.store.DataStoreFactory;
import com.google.api.client.util.store.FileDataStoreFactory;
import com.google.api.services.calendar.CalendarScopes;
import com.google.api.services.calendar.model.Calendar;
import com.google.api.services.calendar.model.CalendarList;
import com.google.api.services.calendar.model.CalendarListEntry;
import com.google.api.services.calendar.model.Event;
import com.google.api.services.calendar.model.EventDateTime;
import com.google.api.services.calendar.model.Events;
And the following is the method taken from the Google sample with some changes:
public void setUp() throws IOException {
httpTransport = new NetHttpTransport();
JacksonFactory jsonFactory = new JacksonFactory();
// The clientId and clientSecret can be found in Google Developers Console
String clientId = "YOUR_CLIENT_ID";
String clientSecret = "YOUR_CLIENT_SECRET";
// Or your redirect URL for web based applications.
String redirectUrl = "urn:ietf:wg:oauth:2.0:oob";
ArrayList<String> scopes = new ArrayList<String>();
scopes.add("https://www.googleapis.com/auth/calendar");
// Step 1: Authorize -->
String authorizationUrl = new GoogleAuthorizationCodeRequestUrl(clientId, redirectUrl, scopes)
.build();
// Point or redirect your user to the authorizationUrl.
System.out.println("Go to the following link in your browser:");
System.out.println(authorizationUrl);
// Read the authorization code from the standard input stream.
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
System.out.println("What is the authorization code?");
String code = in.readLine();
// End of Step 1 <--
// Step 2: Exchange -->
GoogleTokenResponse response = new GoogleAuthorizationCodeTokenRequest(httpTransport, jsonFactory,
clientId, clientSecret, code, redirectUrl).execute();
// End of Step 2 <--
GoogleAccessProtectedResource accessProtectedResource = new GoogleAccessProtectedResource(
response.accessToken, httpTransport, jsonFactory, clientId, clientSecret,
response.refreshToken);
Calendar service = new Calendar(httpTransport, accessProtectedResource, jsonFactory);
service.setApplicationName("YOUR_APPLICATION_NAME");
}
The only problem is with the GoogleAccessProtectedResource class. It is giving me the following error: GoogleAccessProtectedResource cannot be resolved to a type.
Does anyone have any ideas on how I can get around this?
I managed to figure this out. All I had to do was to import the following packages:
import com.google.api.client.googleapis.auth.oauth2.GoogleCredential;
import com.google.api.services.plus.Plus;
import com.google.api.services.plus.PlusScopes;
And replace the following code:
GoogleAccessProtectedResource accessProtectedResource = new GoogleAccessProtectedResource(
response.accessToken, httpTransport, jsonFactory, clientId, clientSecret,
response.refreshToken);
Calendar service = new Calendar(httpTransport, accessProtectedResource, jsonFactory);
service.setApplicationName("YOUR_APPLICATION_NAME");
With this code:
GoogleCredential credential;
credential = new GoogleCredential.Builder().setTransport(httpTransport)
.setJsonFactory(jsonFactory).setServiceAccountId("[[INSERT SERVICE ACCOUNT EMAIL HERE]]")
.setServiceAccountScopes(Collections.singleton(PlusScopes.PLUS_ME))
.setServiceAccountPrivateKeyFromP12File(new File("key.p12"))
.build();
Plus plus = new Plus.Builder(httpTransport, jsonFactory, credential)
.setApplicationName("YOUR_APPLICATION_NAME")
.build();
