CaelenLencioni

This behavior has been resolved and deployed to the production environment as of 3/12/25.

Description

• The $Canvas.assignment.dueAt.iso8601 custom parameter returns the 'Everyone Else' date and not the student specific assignment override when launching an external tool assignment as a student. This is happening for 1.1 & 1.3 tools only when the Assignment Enhancements - Student feature flag is enabled.

Expected Behavior

• The $Canvas.assignment.dueAt.iso8601 custom parameter should return the date that assignment is due for that student.

Workaround

No workaround exists at this time.

Steps to Reproduce

1. Set up a 1.1 or 1.3 tool with the $Canvas.assignment.dueAt.iso8601 custom parameter and the Assignment Selection placement

2. Set up a course with three students

3. Create an assignment with Student A having one due date and the other students having a default due date with a different value

4. Set up the tool on this assignment from the Assignment Selection placement

5. Log in as Student A and launch the tool from the assignment

Result: $Canvas.assignment.dueAt.iso8601 custom parameter shows the default due date

Expected Result: $Canvas.assignment.dueAt.iso8601 custom parameter shows Student A’s custom due date
