LTI AGS implementation in learn was changed to send response status 204, which represents NO CONTENT, when the timestamp sent as part of input JSON is older than the already graded date. But the LTI testing tool does handle this new status code.
RCA:
On analysis found that the new status code change needs to be done in assign-grades.js
