This behavior has been resolved and deployed to the production environment as of 3/25/26.
Summary:
When a student inserts a file in the RCE for a submission, the file does not preview for the teacher in Speedgrader when “Performance and Usability Upgrades for Speedgrader” feature option is enabled.
Expected Behavior:
Files inserted to RCE submissions should be available to Instructor in Speedgrader
Workaround:
- Disable Performance and Usability Upgrades for Speedgrader
- View submission from submission endpoint “/assignments//submissions/”
- Download the file and view it locally (the file can still be downloaded successfully even though it does not preview)
Steps to Reproduce:
Prerequisites: A course with at least 1 teacher and 1 student and “Performance and Usability Upgrades for Speedgrader” enabled.
- Create an assignment with text entry submission type.
- As a student, start the assignment.
- Insert a file in the RCE using insert → document → (upload document) or (user files)
- As the teacher, open Speedgrader for the students submission
- Click the file link to preview
- Note that file does not load and a message “File not found” is shown.
