Hi @jon.zoom - I confirmed that I recieve a ZoomSDKError\_Success response from the createVideoElement call to the ZoomSDKVideoContainer despite having a black video. So no error codes as part of video creation that I can see.

Hi @nraj, thanks for confirming.

Based on the logs provided, this is being caused by exceeding the bandwidth allocated to your SDK instance. You can either try reducing the size of the video elements or reducing the number of elements that are visible to avoid this error.

Also worth noting, we will be adding better error reporting around this scenario in a future release.

Thanks!
