Unable to Upload Video via Frontend in Docker - "Uh oh, we cannot process this video" Error

[yomiyamoto]

Hello all.

I am seeing an issue with uploading any video, similar to the trouble raised in 361 where uploading video on the Sam 2 local deployment fails. This previous issue appears to have been resolved but I'm seeing very similar behavior, with an "Uh oh, we cannot process this video" Error for any clip I attempt to upload.

I have tried local backend deployments via both Docker and waitress and have the same issue.

testing an upload to the backend via curl is giving me what looks like a failed upload:
C:>curl -F "operations={"query": "mutation($file: Upload!){ uploadVideo(file: $file) { path } }", "variables": { "file": null } }" -F "map={ "file": ["variables.file"] }" -F "file=@C:\my_video.mp4" http://localhost:7263/graphql

{"data": null, "errors": [{"message": "'av.video.codeccontext.VideoCodecContext' object has no attribute 'side_data'", "locations": [{"line": 1, "column": 27}], "path": ["uploadVideo"]}]}

Per 364 I saw that I was running the current strawberry-graphql 0.254.0. I have also tried older versions such as 0.239.0 and removed the multipart_uploads_enabled=True parameter, but this hasn't worked either.
