Uploading video via media.upload() not working.

Start with the media.upload() documentation and its supported media types, then reproduce the reported failures with the sample webm and mp4 uploads using the shown TypeScript call. Done means the supported video behavior is verified and either video uploads work as documented or the documentation accurately states their limitations.

I read in the docs that media.upload() supports uploading video types with not much documentation on filetypes, limits or any meaningful information on that.

So I tried adding video uploads to my App:

  const uploadPromises = matches.map(async (match) => {
    const dataUrl = match[1];
    const mediaCategory = match[2];
    const extension = match[3]?.toLowerCase();
    let mediaType: 'gif' | 'image' | 'video' = 'image';
    if (mediaCategory === 'video') {Z
      mediaType = 'video';
    } else if (extension === 'gif') {
      mediaType = 'gif';
    }
    console.log('Uploading media:', { mediaType });
    const response = await media.upload({ url: String(dataUrl), type: mediaType });
    return { dataUrl: String(dataUrl), mediaUrl: response.mediaUrl };
  });
  const uploadResults = await Promise.all(uploadPromises);
  for (const res of uploadResults) {
    finalContent = finalContent.replace(res.dataUrl, res.mediaUrl);
  } 

However I tried uploading a sample webm file and it returns:
Failed to upload media: Error: 2 UNKNOWN: stream error: stream ID 10557; PROTOCOL_ERROR; received from peer

I also tried an mp4 file:
Failed to upload media: Error: 2 UNKNOWN: grpc invocation failed with status 2; unable to poll media URL https://i/. redd. it/xxxxx.mp4 failed to poll media after 5 polling timestamps

I tried different file sizes. Even at 900KB it fails. Not sure why this happens. Can anybody confirm if I am doing something wrong?
I am not sure if I am doing something wrong or not. Not even sure if video uploads is even supported and that docs might need updating.
If I am not doing it wrong then you either need to update docs removing video as supported mediaType to avoid confusion or add the support.
