Description: LTI Deep links may have invalid or missing ID when launched in Ultra Experience Courses.
Steps to Replicate:
- Create an LTI 1.1 or 1.3 tool provider which supports Deep Linking
- Create a Course Content Tool placement and check the box for Supports Deep Linking
- Create an Ultra Experience Course
- Enter the course and click the course contents (+) icon to create a Document > Add Content
- In the Rich Text Editor click (+) > Insert/Add LTI Item
- Use the placement from step 2
- Launch the tool using the browser network inspector to capture the POST request (LTI 1.1) or JSON Web Token (LTI 1.3)
The tool launch will pass a valid Deep Link claim with the valid ID of the document created in step 4.
Observed Behavior:

If this is an LTI 1.3 provider: the resource_link has an invalid ID
Symptoms: For LTI 1.3 the invalid claim from the JWT looks like this:
