**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:

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

```

Some throw this error:

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

```

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

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

```

This is my sessionId: `Ob4FtMyHTlC8qMpHZFYSiA==`

I would appreciate any help.

**Browser Console Error**

**Which Web Video SDK version?**  
VideoSDK: 2.1.0

**Video SDK Code Snippets**

```auto
    try {
      let videoOptions = {
        cameraId: cameraId,
        hd: state.mediaStream.isSupportHDVideo(),
        originalRatio: window.isMobile
      };

      if (state.mediaStream.isSupportVirtualBackground() && virtualBackground) {
        videoOptions.virtualBackground = { imageUrl: virtualBackground };
      }
      await state.mediaStream.startVideo(videoOptions);
    } catch (error) {
      Logger.error('[VIDEO-SDK JS] startVideoStream error', error);
      throw error;
    }

```

**To Reproduce(If applicable)**

1. User A turn on camera and join meeting
2. User B use edge turn on camera and join meeting
3. When enter meeting → use B can’t start video and throw error as above

**Device (please complete the following information):**

- Device: Window 10

Hey @lmtruong1512

> Ob4FtMyHTlC8qMpHZFYSiA==

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, @vic.yang

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

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

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
