Canvas white logo

This behavior is corrected in the 2021-07-21 deploy.

If you hide the second to last course navigation item, and then add an LTI to the course navigation, attempting to use the tabs API to move a course nav item to where the newly added LTI is fails. The response states, "error": "That tab location is invalid".

Expected Behavior

Should be able to set the tab positions of the course to any valid position between the home and settings tabs.


Update navigation by clicking save, then reposition however you would like.

Steps to Reproduce


  • Prerequisite: A course and an LTI to add, such as the Redirect Tool

  1. Update a course's navigation so that a penultimate item is hidden

  2. Add an LTI with a course navigation placement to the course

  3. Via API, try to update the position of any tab (e.g. announcements, etc.) to the current position of the new LTI
