Known Issue: Turnitin Error 124 Object ID missing or invalid
This article describes Turnitin Error 124 Object ID missing or invalid
This issue was noted on the 27th of July 2019, and it ocurred in a module where the assignment was created using the previous Turnitin Building Block (rather than the Turnitin LTI) and the student had not submitted an assignment. On accessing the assignment in the Grade Centre, the Error 124 appeared for the instructor, rather than the message that the assignment was not submitted.
Workaround for staff: Access the assignment via Turnitin.com directly (see knowledge base article).
