When adding Studio media as a submission for assignments with the File Upload submission type enabled and file extensions restricted, an error is thrown stating "Invalid submission file type" after embedding the video.

After receiving the error, students can still submit and the Studio media will be submitted to the assignment without any problems.

Expected Behavior


Since the assignment is a file upload type that restricts submission types we shouldn’t allow studio to bypass the file restriction options so student submit what is required.

It's worth noting that Google Drive and Dropbox both respect the file restrictions when set.


No workaround exists at this time.

Steps to Reproduce

Prerequisites: Published course with a student enrollment that has media in Studio.

  1. Create an assignment with the 'Online' submission type enabled, the 'File Upload' option checked, and the option to restrict file extensions enabled (the file extensions that are restricted doesn't seem to matter).

  2. As a student select the 'New Attempt' button at the top right of the assignment page, select the Studio tab, and choose a video to submit.

  3. Click the embed button on the window that appears and notice the error at the top of the page stating that the submission file type is invalid.

  4. Submit the assignment after the error appears and notice the submission still goes through without any problems.
