LTI Grading via Outcome Service Error

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.

@bpollack1 ‌ This is most likely due to the tool being removed, then reinstalled (or just removed). When a tool is reinstalled, it's tool ID will increment. This means that the new tool needs to be re-launched to get the new sourcedid so that Canvas can map the POX message back to the assignment. You should be updating the sourced_id during each launch. It's ok to store it, but only store the most recently launch sourcedid. If the tool is completely removed, you will also see this error.
