Hi @ChrisChV , this is working well for the most part, good job dealing with the old transcript code!

But I found a bug with the upstream/downstream syncing, and left a few nits/change requests too.

Why does this error need to be caught now? Seems a little dangerous.

I'm seeing a bug when I sync a LibraryBlock video with transcripts from an upstream video.

Steps to reproduce:

Create a library video with transcripts (here, I imported them from the example youtube video).

Publish the library video.

Copy it to the clipboard.

Paste into a course.
Note that the transcripts are displaying fine here.

Re-edit the library video, and replace a transcript. (Here, I replaced the English one, I don't know if replacing others causes the same issue).

Return to the course LibraryBlock, and refresh to see the "updates available" button. Click it.
Note that the upstream video preview shows its transcripts fine, but the downstream (course) video preview doesn't show its transcripts anymore.

Accept changes.
Note that the course video no longer shows its transcripts, but if you edit it, you can see they're still there.

I think this is related to openedx/modular-learning#246

@ChrisChV That could very well be.. however I don't think it's resolved by @DanielVZ96 's #36173, but it's also possible that I didn't merge conflicts accurately. cf my merged branch.

@pomegranited To be safe, I will wait until #36173 is ready to fix this bug.

No worries @ChrisChV , thank you for keeping an eye on this issue.

👍 Thank you for making those changes @ChrisChV ! Code looks and works great.

I tested this using the testing instructions from feat: Enable transcripts for video library [FC-0076] frontend-app-authoring#1596.
I also tested "duplicating" video blocks with transcripts in courses, and they worked too.
