I am trying to submit a grade using the outcomes service in LTI. I am getting an error saying that "Assignment is no longer associated with this tool" even though I have not changed anything in Canvas. I successfully created an External tool that is accessed via the assignment selection and a correct LTI launch is created. The student can take the assignment in our externa tool. I retrieve and store the lis_outcome_service_url and lis_result_sourcedid all without any issued. Below is the outgoing and incoming XML data. Any suggestions on why this error is occurring? Thanks.

send xml:
