500 Error getting data: Unable to retrieve modules for course: <Response 401>

500 error in Canvas

Possible causes

 

Holding both a teacher and student role in the course

When two different email addresses are associated with a single Badgr account and are used in different roles in Canvas, this error may occur. When this happens, the system doesn't know which permission (teacher or student) to serve to the user. For example, an instructor uses "badgr@myschool.edu" in the role of instructor in a Canvas course. The instructor has added an additional email address,  "teststudent@myschool.edu" to their Badgr account.  When the instructor uses the additional email address "teststudent@myschool.edu" in a student role in the same Canvas course they encounter this error.

Remedy: Remove the test student from the course or disassociate the email address from the Badgr account.


Course and/or modules are not published

Remedy: Publish the course and modules, ensure you're enrolled as a teacher.


Canvas authorization token

Occasionally, the Canvas authorization token isn't working in a course. If the above two troubleshooting processes don't resolve the issue, then this is likely what's going on. 

Remedy: Contact support@badgr.com to have your authorization token reset. In your email, describe the error, provide a screenshot of the error message and the course URL, and include the fact that you've gone through the troubleshooting process so that the support team doesn't direct you back to this page.
