Error with missing video transcripts

[samuelallan72]

The demo course at the current master branch includes references to video transcript files which do not exist. This causes errors, such as failing to export the course or failing to reindex the course.

Example error:

File does not exist: video-transcripts/93eb0b27dd8c48319fdb0258193958dd.srt

The references need to be removed or updated, or the missing files added.

Reproducer

• download the demo-course.tar.gz from the dist directory on the master branch
• import the demo course into an Ulmo openedx instance (the issue is visible on older releases too, but this particular export error appears to be newly surfaced on Ulmo)
• export the course, and verify you see an error, and the course fails to export

Workaround

A workaround for now is to delete the problematic video transcripts from LMS Django Admin -> Edxval -> Video transcripts.

@samuelallan72 thanks for this report. I actually brought this up with @ormsbee to address the export issue - export shouldn't fail because of missing transcripts, and I believe he has a fix in the works for edx-val.

In the meantime, Samuel, do you think there's a way we can fix this issue in the packaged tarball for this course? I couldn't figure it out :\

[samuelallan72]

@sarina I haven't had much time to investigate unfortunately. It should be possible; hopefully it's just a missing transcript reference somewhere.

[sarina]

Yeah, probably, I also haven't had time to figure it out... hopefully we can get the edx-val fix in Verawood, then I'll mess around with import/export once I have a working flow.

@samuelallan72, @sarina: I'm trying to get one more PR into review for Verawood today, but I will prep a fix for this as the next thing on my list. Sorry for the inconvenience.

[sarina]

That's awesome, ty @ormsbee !

@samuelallan72 just fyi this will be in Verawood and also backported to Ulmo, we'll let you know when this is released if you want to update your instance.
