​​​​​Canvas Grade Passback Publishing Error Code Explanations

When an instructor publishes grades from Canvas to WebCat they will receive an email once the process has run. This email will reference the course and course number, the total number of grades submitted and the number of errors if any. A Batch ID number will also be included which is important should you need support, you will be asked to reference that number.

It is important that after uploading your grades, you log into WebCat to ensure your grades published properly.

Sample Email

After submitting the grades you will receive an email containing detailed information including details about any errors. If you do have errors, see the table below for possible solutions. If you have cross-listed your courses, then you will be sent an email for each course.

The Batch# listed in the email is the easiest way the technical support admins can track down errors so if you submit a support ticket please include the number in the ticket. See the table below for the types of error you might see and the solution. Additional information about how to correct the errors in your submission are in the KB article (Canvas Grade Publishing to WebCat ). If you need immediate assistance please call the Service Desk at (603) 862-4242.

  • Message with a specific number of "Unpublished" grades.
