Error Accessing a course from Studio

tuananh-pham · August 4, 2020, 12:25am

I’m getting this error consistently accessing a course I created from Studio

Here are the CMS logs during that action:

It appears that the import fails while trying to import a section that contains a dot character (“Bài Học Số 4.1”).

Have you tried renaming that section to remove the dot character?
What version of Tutor are you running?
Are you importing a course that you exported from Open edX?
Can you share this exported course file so that we can try to reproduce the issue?

Hi regis,

We tried removing all the forum key with the dot character, and the issue is gone since!

We’re having the same problem. It comes and goes without us doing anything. Same key must not contain ‘.’ error, but the key has a bunch of HTML tags.

But what are forum keys? Where do they come from? How do you edit them? We can’t see anything related to the error in the course export, yet if we re-import the course, the problem occurs again after a while.
