Zoom Web SDK UI not displayed after upgrade to v1.8.5

The Zoom UI was working fine for v1.7.10. When I upgraded the SDK version to latest 1.8.5, The UI stopped working, nothing is displayed on the screen.
Downgraded again to 1.7.10 and it is working fine. All APIs are working.

No error message shown in console.

Which version?

Device (please complete the following information):

  • Device: MacBook Pro
  • OS: MacOS BigSur 11.1
  • Version: Zoom SDK 1.8.5
  • Browser: Chrome

Hey @nilesh.bunde,

Thank you for reaching out to the Zoom Developer Forum. Are you seeing any errors in the browser console? Please share them if so. If not, are you able to share a public git repo demonstrating the issue?


Hi @MaxM, Thanks for the reply.
I didn’t see any errors in console. Here is some code snippet. I’ll check if I can share the code in git with you.

  .subscribe((signature) => {
    this.signature = signature;
    const meetingConfig = {
      meetingNumber: this.meetConfig.meetingNumber,
      userName: this.meetConfig.userName,
      signature: this.signature,
      apiKey: this.meetConfig.apiKey,
      userEmail: '',
        typeof this.meetConfig.passWord === 'undefined'
          ? ''
          : this.meetConfig.passWord,
      success: (res) => {
      error: onFailure('Failed to join call after creating it'),
      leaveUrl: this.meetConfig.leaveUrl,
      isSupportAV: true,
      debug: false, //optional
      isSupportChat: false,
      isSupportNonverbal: false,
      success: (res) => {
      error: onFailure('Failed to create Zoom call'),
  }, onFailure('Failed to get signature to initiate call with'));

All 3 onFailure() functions are getting executed
Also I wonder if it is related to JQuery dependency?
I was checking the websdk-sample-angular


Here tommy has removed JQuery dependency, but in out project we have used JQuery. Please let me know if that is the case.

Hey @nilesh.bunde,

Thank you for the update. Good catch! That’s correct, the latest version of the SDK (1.8.5) no longer requires jQuery as a dependency. Please try removing that and testing with a setup that’s closer to the sample app implementation to see if that resolves your issues. I’m not seeing anything in your code that would be causing this otherwise.


Hi @MaxM,
I removed JQuery dependency from the code, but the issue is still there. I also tried updating Angular to the latest version v11.

Hey @nilesh.bunde,

Can you try checking your Z Index on your site. I wonder if the Web SDK is running in the background of your site since the jQuery logic has been update.

Try giving the Web SDK root element a z-index of 1000.

Let me know if that helps.


Hi @tommy
I have already tried that before. UI is still not loaded. In SDK v1.7.10 when starting a video call, zoom starts loading its library files but in the latest version, these files are not getting loaded.

Here are the logs for Latest version if that is helpful

Network tab

Did you resolve this problem?
I faced also problem.

No, Not yet :frowning:

Can you pls contact with developer team? :slight_smile:
I’m going to contact with them.
I should resolve this problem assp.

sorry I didn’t get which developer team?
If you are facing issue regarding adding language json.
eg. GET http://localhost:4200/node_modules/@zoomus/websdk/dist/lib/lang/en-US.json 404 (Not Found)
You can add ZoomMtg.i18n.load('en-US'); and it will work.

Ref. websdk/README.md at master · zoom/websdk · GitHub

Hey @mtroz310 , @nilesh.bunde ,

Checkout this thread on the language path issue:

Let me know if that helps! :slight_smile:


Hi @tommy,
I tried this fix but it is still not working. I don’t think this is related with lang. The code execution is not reaching in success method of
ZoomMtg.init({ success: (res) => {
I was able to load en-US
See this screenshot

Hey @nilesh.bunde ,

If the ZoomMtg.init function is not being called, please ensure you have called the preload functions before hand, example (lines 7 and 8):


Hi @tommy,
I tried this solution but it is still not working. I tried adding

ZoomMtg.setZoomJSLib('https://source.zoom.us/1.8.5/lib', '/av');

in ngOnInit and constructor as well. It is getting loaded as shown in the console screenshot in above comment.
[Zoom Web SDK UI not displayed after upgrade to v1.8.5 - #8 by nilesh.bunde]

ZoomMtg.init function is getting called but it immediately goes to onFailure('Failed to get signature to initiate call with'));

Hey @nilesh.bunde,

Anyway you can provide your code in a github repo, or a sample repo with the issue so we can take a look?
