Import course stuck on "Uploading"

[tech_mil]

Hello,

I am having a problem uploading a course from another platform and it gets stuck on “uploading” right at the start. Most courses work but I am having a problem with thi

I have investigated in the debug and found where it fails but I am not sure where to go next from here.

I noticed that the course number is different before and after the traceback (ORG3 and ORG1). Not sure if related but I did try to keep everything the same when importing the course. I have tried it quite a few times now.

For now I am uploading this course through command line but it would be great to get this working.

If anyone has any suggestions I would appreciate it.

@dave any advice on import issue?

[dave (Dave Ormsbee)]

@tech_mil: Please go to your Django admin at:

http://local.openedx.io:8000/admin/split_modulestore_django/splitmodulestorecourseindex/

Find the entry for this course and click it. Can you please put the detail view here? It should look something like:

Thank you.

Sorry for not replying earlier.

Here is the image of the course that I was able to upload using command line. I can upload the one that got stuck later.

I had to redact some stuff but where it is supposed to contain organization, it is correct and can be assumed to be “organization” like previously and the same for course number being ORG1

[dave (Dave Ormsbee)]

Please try looking up this course key (the “course-v1:…” piece) in the course_overviews_courseoverview table (as id) and in the split_modulestore_django_splitmodulestorecourseindex table (as course_id). Are there entries that differ only by capitalization, e.g. (“course-v1:my_org+my_course+run1” vs. “course-v1:My_org+My_course+Run1”)?

The course overviews table is case insensitive, while the split_modulestore table (and MongoDB) are case sensitive by default. This sometimes causes weird lookup issues when entries differ only by case.

I did not find any difference in those tables however we looked deeper in the course zip file strucutre and found that some files has differences which could be the problem if you could confirm?

The left file is the version that was successfully imported and then exported from the website and the right is the original course to be imported. We found that a lot of the course files had differences like this.

Something else to add, I tested the import on my local machine instead of on the server and I was able to get it to upload! Bu this was on a local instance of the platform.

Also, would an edx version difference have any affect? Our platform is on latest version of tutor and edx however the platform that the course came from may be one or two versions behind.
