Hi @yakov.yarmo ,

Thank you for the attachment. What browser/version of the browser(s) are you seeing this issue in, and is it happening in multiple browsers? Additionally, what is triggering this error? Are you attempting to enable gallery view, or show multiple videos, when it occurs?

Thanks,  
Rehema

I used the react demo code from:

> **[GitHub - zoom/videosdk-web-sample: Zoom Video SDK web sample](https://github.com/zoom/videosdk-web-sample)**
>
> Zoom Video SDK web sample. Contribute to zoom/videosdk-web-sample development by creating an account on GitHub.

And in config-overrides I disabled the config.headers to simulate a browser that doesn’t support SharedArrayBuffer.

I’m using chrome Version 114.0.5735.133 (Official Build) (arm64)

Hi @yakov.yarmo ,

I disabled the headers as well and ran the code, but was not able to reproduce your error. If you haven’t already done so, can you go into App.tsx and comment out the current ‘component’ line (~259) and add in ‘component={VideoNONSAB}’ underneath the line that reads 'path=“/video” '. This is to ensure the app is rendering the correct video component and seeing if the error still occurs.

Thanks,
