Sub assignment submissions objects not generated when blueprint syncs

Issue Documented: 2025-01-31
Canvas

This behavior has been resolved and deployed to the production environment as of 4/9/25.

Description

  • When an account has discussion checkpoints enabled, if a user creates a discussion in a blueprint course that uses that option, and syncs the discussion to an association course, the discussion in the association will not generate sub assignment submissions objects. This causes the gradebook not to load, and produces an error when accessing the submissions API.

Expected Behavior

  • The discussion in the association should have sub assignment submissions objects.

Workaround

  • Run the SLM

Steps to Reproduce

  1. Enable discussion checkpoints in the account features

  2. Create a blueprint course

  3. Create a course, and associate it to the blueprint course

  4. Add at least one student to the association course

  5. In the blueprint course, add a graded discussion, and enable discussion checkpoints

  6. Sync the blueprint changes

  7. In the association, note that the assignment submissions API produces an error when including sub_assignment_submissions. Also note the error in the gradebook
