I use zoom sdk for many years, today I upgrade sdk version from 2.12.0 to 2.17.0, and found there is a whiteboard feature, when I using whiteboard feature, I got many CORS errors

  1. add comment
  2. star whiteboard

my code:

this.joinMeetingPromise.then(response => {
      const { signature, zoom_id, password, sdk_key } =;
        leaveUrl: this.backUrl(),
        isSupportAV: true,
        isSupportPolling: false,
        success: () => {
            signature: signature,
            sdkKey: sdk_key,
            meetingNumber: zoom_id,
            userName: UserHelper.formatName(currentUser),
            passWord: password || '',

Thank you for posting on the Zoom Developer Forum. To start, have you followed our guide on Improving Web SDK Performance? This problem may be happening because cross-origin isolated or Origin Trials are not applied. I should note, one or the other is sufficient. You do not have to implement both. More details on this topic here:

Whiteboard is supported for the Web SDK. Please see the list of supported features here :

I’m facing the same problem, how did you fix it?

No one is responding, it is a critical issue

@into.devteam and @lcsandrade ,

Are you still experiencing the same issue with the Meeting SDK? This problem should have been resolved in the latest release. Please update and let me know if the issue persists.

Unfortunately, it is still exists even in 3.1.6

Okay, let me test on my end and I will create a support ticket to have this investigated if needed.
