During import of a course exported from edx.org, videos are not re-created

[frohro]

I imported a course here and on edunext, and the videos appear on edunext, but not here. I have been able to add them by hand, but that is a bit painful.

Maybe there's a custom xblock present on edunext that's not included in the base install of openedx-docker. Can you email me the course, or just a sample of the course?

[regisb]

Also, can you give me the complete log produced by the lms and lms_worker during import? If some xblocks are not recognized, there should be some error logs produced.

I'm sorry I got too busy with other things here, and now the logs are only back to October 5, but this occurred before that.

[regisb]

It would really help if you could send me a sample exported course, or even just a piece of the course. Otherwise I won't be able to reproduce and solve it.

Did you get the link to the course I emailed you? Rob

Hmmmm no I didn't. Did you send the email to the address listed on my profile? https://github.com/regisb

Managed to reproduce the issue. Importing fails for videos with the following stacktrace:

 Traceback (most recent call last):

 ValCannotCreateError: {'duration': [u'This field may not be null.'], 'client_video_id': [u'This field may not be null.']}

However, import was successful (including for videos) on a Ginkgo platform. It is confirmed that eduNext was running Ginkgo as well, which explains why importing the course there was successful.

So the conclusion is that videos from older courses on edx.org are not compatible with Hawthorn :-/ This is a problem with upstream Open edX, so I'm closing this issue here for now.
