My students are uploading files as part of their assignment from their Google Drive. For some students, there is so issue. But for other students the message I get says "This file contains HTML and cannot be previewed. Please download to view." So I try to download the file, and I still cannot open or view the file. I checked share settings and watched the student upload the file. Everything seems to be working. Any ideas on why I cannot get some students' files? The students end up sharing the files with me through Google drive.
Others have had a similar issue going back to August of 2020. You can read their posts here, tho I did not find a solution. This file contains HTML and cannot be previewed. P... - Instructure Community (canvaslms.com)
I did a quick Google search, and the issue may not be with Canvas, but with Google Drive. I found a similar issue posted to Google's forums.
Their solution was to change the share permissions in Google before submitting to Canvas. It might be worth a try.
