Troubleshooting: Couldn't find valid settings for this link
Problem:

If you've used the external tool feature to place a view of a badge right in a module (to collect evidence or not) you may experience an error message.
Rarely, the configuration saved in Canvas for module item placements of a badge within a course becomes corrupted. This is easily corrected by reinstalling the Canvas Badges/Credentials LTI and reconfiguring the module badge placements. No data about your course configuration or awarded badges will be lost.
Solution:
Closely follow these steps to correct the error:
- Remove the external tool placement in all modules and in all courses where it is being used.
Note: If this step is skipped, the error message won't clear. - Uninstall Canvas Badges/Credentials from the course, sub-account or root level.
- Reinstall the Canvas Badges/Credentials at the course, sub-account or root level.
- Add the external tool placements in modules where desired.
- Observe that the tool is working properly.
Reinstalling Canvas Badges/Credentials won't affect ongoing courses. When the app is re-added to a Canvas instance, existing configurations and badge assignments will automatically be re-established.
- The only exception is the Canvas Badges/Credentials external tool placement(s), which should be removed manually prior to reinstalling the Canvas Badges/Credentials app to clear the error: Placements made with a previous install of Canvas Badges/Credentials will no longer work with a new install.
