Improved Handling of User Data for Anonymous Grading

When querying submissions for assignments that are actively using anonymous grading, the user field returns null. This change helps preserve grading anonymity by preventing access to identifiable user information while anonymous grading is active.

2025-05-17

Beta Availability: 2025-04-21

Announcement Date: 2025-04-18

GraphQL limits are added to Canvas to strengthen Canvas's GraphQL implementation against various denial of service attacks.

• A query cannot have a complexity over 375,000. (To see how complexity is calculated look at https://graphql-ruby.org/queries/complexity_and_depth#connection-fields.) Query strings exceeding 5000 tokens will result in an error.
  
  

Changes that won’t trigger errors, but may return fewer values than expected:

• The default page size for returned results is now set to 20. Queries that would previously return unlimited results, by default, are capped at 20. See the GraphQL API Pagination section for more details.
• Users can request a higher page limit (up to100) in their query.
