LTI Request Error

If you're seeing this error, Cadmus couldn't connect to the Learning Management System (LMS), e.g. Canvas, Blackboard, or Moodle, to open your assignment. 

Potential causes

  • Cadmus isn’t being accessed directly via the LMS.
  • Cadmus may have been set up incorrectly in your LMS.
  • Cadmus doesn't recognise the user role passed by the LMS.

To fix this problem:

  1. Log out from the LMS.
  2. Close and reopen your browser.
  3. Log back into your LMS and access Cadmus through your LMS (not through a bookmark or URL).
