`stream.startVideo` freezed on Edge and throw error

Video SDK Web
1

Description

  • On some machines using the Edge browser, starting a video stream fails intermittently.
  • Calling stream.startVideo() sometimes freezes for a long time before throwing an error, and in some cases, it remains frozen indefinitely.
    (Other browsers work fine)

After an extended period, some devices throw the following error:

Uncaught TypeError: Cannot read properties of null (reading 'Set_WaterMark_Info')
    at f836a31f-95dd-4ee7-84c2-a8b983ef9ffc:24375:20

Some throw this error:

name: 'Empty error',  message: 'no elements in sequence'

As a result, when attempting to render the video, the following error occurs:

Uncaught (in promise) {"type":"INVALID_PARAMETERS","reason":"user is not sending video"}

This is my sessionId: Ob4FtMyHTlC8qMpHZFYSiA==

I would appreciate any help.

After analyzing the session ID, we identified some suspicious points and may need additional logs for further investigation.

Would it be possible to integrate client-side telemetry and report detailed logs to us for troubleshooting?

Thanks

I’ve added telemetry. Can you help troubleshoot with this session IDs: Akzldh0gQw+d8uWGPCkNFg==, r4r1H2bYRiCx9Nb1umi/Ng==

@vic.yang I also encountered a similar case.

Hey @namlv , @lmtruong1512

Thanks for sharing the additional session IDs with us.

We have identified the root cause and will fix it in the upcoming release (2.1.10).

To further determine the root cause, can I confirm with you whether you have manually set the node-id attribute on the video-player element?

Thanks
Vic

@vic.yang Thank you, hope the release comes soon!

Yes, I have manually set the node-id on the video-player. Can I temporarily remove it as a workaround?

Thanks

I have manually set the node-id on the video-player .

This could be the reason for the error.

Video SDK manages the node-id as it is associated with some internal states. Manually setting it may cause state mismatches, leading to issues.

Thanks
