I encountered an error Uncaught TypeError: Right-hand side of 'instanceof' is not an object on my console.
This error is from Ext.toolbar.Toolbar class located on node_modules/Toolbar.js of my universal app. I use open tooling to generate my app.
Upon checking the Toolbar.js, the Ext.toolbar.Separator is in the uses property. Supposed to be the ext classes shouldn't be modified and I don't know why this error suddenly occurred.
I build the app using sencha app build dev/testing mode and it succeeds but it has the console error above. When building on production, it fails also and outputs the same error above.
From sencha app build --prod output:
TypeError: undefined is not a valid argument for '''instanceof''' (evaluating '''component instanceof Ext.toolbar.Separator''')
Can somebody explain why this error occurs? Any help will be appreciated. Thanks
Change your code to:
if (component.xtype === 'tbseparator') {
...

My react application is working fine until I wanted to wrap it up and deploy it. The build via vite build is successful. However, when the built folder "dist" is deployed and served, it says Uncaught TypeError: e is not a constructor.
After hours of debug, I can confirm that it's the aws-sdk that is causing the issue. In particular, the following code:
const s3 = new S3({
accessKeyId: VITE_ACCESS_KEY_ID,
secretAccessKey: VITE_SECRET_ACCESS_KEY,
region: VITE_REGION,
});
I think the new S3(...config) here corresponds to a line that reads o = new e; in the compiled index.bad38efb.js file that gives the Uncaught TypeError: e is not a constructor error.
Ultimately the question comes down to, is there any alternative that I could authenticate with s3 or does anyone know how to resolve this problem? Please let me know what extra information could I provide to answer the question.
Had the same issue, although harder to debug since I was not getting any errors in building.
Solution is to move to the v3 version of the SDK which is better maintained (and has other benefits too).
I am trying to create a desktop application using Electron and React.
I set the basic settings using electron-react-boilerplate.
https://github.com/electron-react-boilerplate/electron-react-boilerplate
However, I continued to receive can't resolve fs module not found error.
To solve this error, I performed the method suggested in document https://electron-react-boilerplate.js.org/docs/native-modules/#native-modules-in-electron-react-boilerplate. (activate node integration)
Then I got an error Uncaught TypeError: Cannot read properties of undefined (reading 'ipcRenderer'). but strangely, an error warning window appears, but the app runs normally.
How can I get rid of this error?
currently, i comment all of following code in src/renderer/index.tsx
// calling IPC exposed from preload script
window.electron.ipcRenderer.once('ipc-example', (arg) => {
// eslint-disable-next-line no-console
console.log(arg);
});
window.electron.ipcRenderer.myPing();
Currently, I am building a MobileApp with React-Native and everything works fine until today :/
Unfortunately today the app throws an error (see below) after a successful build!
[TypeError: undefined is not an object (evaluating 'row[OBJECT_COLUMN_NAME] = key')]
BUT this error only appears in the normal mode -> if I switch to the debug mode everything is working without any further problems.
So after that, I started searching the trigger of this error and I found it (See below)
Your_App/node_modules/react-native/Libaries/polyfills/console.js (Line 449)
But as you can see that isn't from me it's from React-Native and I am not able to resolve this problem
After a long research on the internet, I couldn't figure out anything because nobody has got this error yet :/
But I think it has something to do with the newest react-native firebase version 6.0.0 (https://invertase.io/blog/react-native-firebase-v6)
Because it fails near there (See below)
Note: After recreating the app (not hard with git) the error appears again after a while :/
Note: A empty App still works on my engine
What do I use:
react-native 0.61.5
java 13
(All used libraries)
I would appreciate help ^^
Thank you
After I filled my code completely with console.logs... I found out that React Native does not work with console.table in non debug mode.
This is easily fixed by using console.table only when the app is in debug mode. Just check if the debug mode is enabled ^^
const isDebuggingEnabled = (typeof atob !== 'undefined');
That's it
My code works on development mode, uncompressed. But when I use grunt's minify functionality and run the app in production mode, I get that error: Uncaught TypeError: angular.module(...).run(...) is not a function.
When I look into the error in Google Chrome Developer Tools, I get what you see in the screenshot. Does anybody understand where the problem is?
I am using Angular 1.4+ in Angular-Fullstack. The error occurs in vendor.{{randomstring}}.js.
Thanks for any support!
You have 2 issues here.
Dependency injection. You can edit manually the archives or use https://github.com/mgol/grunt-ng-annotate this will do this automagically for you.
Concatenation. Check this grunt plugin https://github.com/gruntjs/grunt-contrib-concat the issue here is javascript dont understand when a function end/start because dont have a separation mark, check where the error is.
})(function(a,b) {
It should be:
});(function(a,b) {
Check the "Concatenating with a custom separator" example of grunt-contrib-concat
Im here trying to find out how to solve this little problem.
I've been working with Sencha Touch v2.1 to create all my views and stuff.
After that, i started working with Sencha Command v3.0.0.250 to improved performance in my app, but after Sencha C. do its own business and try to open the index.html (throw IIS) something like that occurrs. (using chrome)
"Error evaluating http:// localhost/Production/app.js with message: TypeError: Cannot call method 'substring' of undefined "
Whats going on? What substring is talking about?
Thanks in advance!
Ensure that you see no warning messages in the Console since you have to add requires following by the classes you will be using before building it.
