Occasionally you may see an error when opening a Hypothesis Canvas assignment: Hypothesis couldn’t find the file in the course. Students may also encounter a similar error: Couldn’t get the file from Canvas
The usual fix, and the first one to try, is to re-link the PDF to the assignment. Occasionally, however, this does not resolve the error. In these cases, you will likely need to re-upload the PDF into Canvas and re-link the Hypothesis assignment to the re-uploaded file.
1. Re-upload the file to your Canvas course site
From the Canvas sidebar select Files and confirm that the PDF is available (Note: If the file is missing, you will need to upload a new copy of the PDF to Canvas Files and skip to step 2):
With the file selected and highlighted, click the Download button to download the PDF to your computer:
Now, click the Upload button and browse to the PDF that you just downloaded above. You will be re-uploading this file back into you Canvas course:
When prompted, select to Replace the existing file with new PDF you are uploading:
Confirm that the PDF re-uploaded with no errors.
2. Edit the Assignment
From your Assignments page, find the assignment, click the 3 dots at the right, and select Edit:
In the Edit Assignment window, click the More Options button:
3. Re-attach the PDF to the assignment
From the Configure External Tool window, select Hypothesis:
On the next screen, click Select PDF from Canvas:
4. Save the assignment
Scroll to the bottom of the assignment page, and click the Save button to save the updated assignment.
