ReferenceError: Can't find variable: OffscreenCanvas

Hello! I have the following setup:

“Alice” is running the Zoom WebSDK and connecting to “Bob”, the meeting host using a native Zoom client. Alice is able to successfully join Bob’s meeting, but when Bob tries to share his video, Alice receives the error “ReferenceError: Can’t find variable: OffscreenCanvas”. Alice is then shown a black screen. Please view the screenshots at the end for the error.

As an initial test, I attempted to instantiate a new instance of “OffscreenCanvas” from the console in the dev tools, and it was successful.

Which version?
OS: Ubuntu 16
Browser: Safari11 - AppleWebKit/605.1.15
@zoomus/websdk version: 1.8.1


Any help would be much appreciated!

While I didn’t figure out this specific problem, I saw in the Zoom code that it does it’s own polyfill of sorts for OffscreenCanvas, so I deleted my browser’s version of it from the window and then it worked fine.

Happy to hear you got it sorted out! :slight_smile:

Did you still have an additional issue you want us to look into?
