React fetching timeout - reactjs

I have a react app with express backend. When I make a post request from react, I can see the query being run in the database. however, when the query takes more than 2 minutes to run, React fetch process would stop, although the query would still keep running in the database and would return the result to express (I know it returned data to express because I had a console.log in the express code to show data length which did show up in the console after the query stopped running).
In the front end, it would show the following error. Anybody has any suggestions on how can run large query from React and get the data back without timeout? I have tried all the timeout settings, etc. thank you

#firebase/firestore: Firestore (9.14.0): Could not reach Cloud Firestore backend. Connection failed 1 times

I am trying to run this code locally with my own instance of a Firebase Firestore database and I am running into this error enter image description here. As a result I am not able to read or write any information from the database. Does anyone know how to resolve this issue?
I have tried modifying the firebase.config.js file with various different parameters with regards to creating an instance of a connection with the database but I continue to get this error.

React error: request failed with status code 400

I am following Bezkoder tutorial in the link to create a simple CRUD database using React, NodeJS, Express and MySQL: [https://www.bezkoder.com/react-node-express-mysql/#React_Nodejs_Express_MySQL_Architecture
I've successfully created the backend and tested read, write and delete of records using POSTMAN. I've then created the React frontend, which uses Axios - it compiles OK, and displays a web page in my browser. This page will read records from the database OK, but when I try to add new or amend existing records, it doesn't work, and in console it displays "Request Failed with status code 400" error. The full error message in console is as follows:
Console error
I'm not sure what the error means or how I might go about troubleshooting further. Could anyone point out to me how I can troubleshoot this further or what other info you'd need to help me?
I was expecting the React frontend to be able to add new records and amend existing records.

Firebase Quota exceeded working on my app

I'm working on my react native app for a university project and today I got this error:
[Unhandled promise rejection: FirebaseError: Quota exceeded.]
And when I open firebase I can't see my database, I see an error during the loading files.
I created the firebase project yesterday, and if I check the reads and writes I see 1605 reads and 3 writes.
Yesteday I had the same issue and I solved it by creating a new database and connect it again to my react native app, but I can't do this every day, how can I work on it without having this trouble anymore?
I just realized that the problems are caused by the timestamp methods, when I try to read the createdAt label and to convert it with getDate I get too many reads

Solr data import - refreshing status gets different statuses

I am running a Solr cloud consisting of five servers. I start a dataimport from the Solr Admin UI. When I refresh the status I do not get a consistent result - one time I might get the status of the currently running import, another I might get "No information available (idle)", and another I might get the status of a previous attempt which succeeded/failed". Am I correct in assuming that this is happening because the import is handled by a single server but the status request is going to all of the servers so 80% of the time the request will be answered by a server that is not running the import?
Is there a way that I can just get the status of the running import? I tried sending the status request to the server that is running the import and I still get different messages each time I make the request.

Getting all entries from a database that start with letters using HTTP request

I am writing a simple filter function that sends a request and gets all entries that partially match the query. Desired behavior is if do a GET request localhost:3000/employees?email=mai I would like to receive all entries from a database starting with mai. Is there any way to construct an http requests for the desired behavior from a front-end part of the application? Perhaps some headers that tell the server that the search should not be strict? I have tryed googling it but failed. I am using AngularJS fro front-end and json-server as a back-end mock server
Up to my understanding if you filter data in front End you will get only that data filtered which you are showing. In the other hand If you do this using Query(Back End) all the data get filtered in DB.
