@svickers2 would be deeply grateful for your input on this... I'm wondering if the doOutcomeService function in the old PHP IMS library could be related: https://github.com/IMSGlobal/LTI-Tool-Provider...

@svickers2 any chance you can take a look at this and share your thoughts?

Question here -- if the signature is not correct there should be no XML returned, correct? I am troubleshooting an LTI passback error, but since I am usually getting other errors back I am thinking OA...

Did you ever get an answer on this? Having a similar issue.

You will see that we're getting different errors each time. In one case it says "user is no longer in course" in another "assignment is invalid". In both cases there haven't been any changes to the us...
