I am trying to integrate blackboard REST APIs with our application. Where i used
Blackboard end pints to delete student grades and corresponding grade column.
I deleted grade by setting the 'score' attribute as null in the request body.
Then i tried to delete coresponding grade column and i am getting following error
"message": "Cannot delete Column _171773_1 in Course _12822_1, has associated grades."
Could you please let me know the reason for this error. I highly appriciate if you can guide me how to delete student grades and assignment without any error.
