window.getSelection() is null React Error with SDK 1.9.0 when Waiting Room is on

Description
If waiting room is turned on with SDK 1.9.0, I am receiving an error in the console stating window.getSelection() is null. This only happens if the waiting room is on while the attendee is trying to join. If they are manually placed into the meeting room when the meeting is already in progress, this doesn’t happen.

Error

TypeError: window.getSelection() is null

After some experimentation, this only happens if the SDK is embedded in an iFrame. It’s not supported officially by Zoom, so I’ll see if there’s a workaround…

Thanks for sharing your findings @alexmayo ! :slight_smile:

No worries.

Just curious! Is there a reason that Zoom doesn’t officially support using iframes with the WebSDK? We’ve been using it for a while now and 99.9% of the features work exactly as expected, there are just a few edge cases like my issue above.

Cheers,

Hey @alexmayo ,

The Web SDK was not designed to work within an iFrame so there could be some issues. We are working to make the Web SDK more flexible to give the developer the ability to configure / customize it further, instead of having to use an iFrame. Stay tuned:

Thanks,
Tommy
