Engineers are currently investigating the issue.
Description
-
When a rubric has a criterion with a null long description, attempting to view the rubric in BETA will produce a page error with an unknown keywords: title caused by unknown keywords: title error in /error_reports
-
In my testing, copying a rubric with a criterion with a blank long description from another course is the easiest way to end up with a null long description (omitted long descriptions are set to an empty string when creating rubrics in the UI or via API).
-
Expected Behavior
Instead rubrics which display successfully in test and production should display in beta.
Workaround
No workaround exists at this time.
Steps to Reproduce
Prerequisites: Two courses in beta.
-
Create a rubric in one of the courses with a criterion with the long description left blank.
-
Copy the rubric into the other course then attempt to view the rubric in the course and note the page error.
