If you encounter this error, please update the Submission Type settings in your assignment to ensure CoGrader can successfully export submissions to Canvas.
Follow the steps below:
Step 1: Go to your Dashboard and select the course
Step 2: Select the assignment
Step 3: Click on 'Edit'
Step 4: Tick the option 'Website URL' and save
Done! Now you can go back to CoGrader and try to export the submission again.
Other Errors
If you see an Export Error next to one or more students after Exporting to Canvas, follow these steps:
Allow multiple submission attempts
In Canvas, go to your assignment Settings and set Allowed Attempts to Unlimited.
This prevents export errors when students resubmit or when CoGrader tries to update feedback for a previously graded submission.
Several teachers have found that this resolves the issue entirely.
Retry Export
The export should complete successfully.
