fix: missing transcript should not fail export#606
Merged
Conversation
Before this commit, a missing transcript file would raise a FileNotFoundError from get_video_transcript_data() when the file was missing. This can happen if there are references to edx-val video_ids in the course content, but the corresponding transcript files were never properly exported. This exception was never handled anywhere in edx-val, so it would fail the course export entirely. Now we catch the FileField's underlying FileNotFoundError and re-raise a TranscriptNotFoundError, and then catch that a couple layers up in create_transcripts_xml(). This means that a missing transcript will not fail other transcripts for the same VideoBlock (though in practice, if one is broken, the others are likely broken as well).
