When students are launching into our tool the value of lis_result_sourcedid is being passed as "{". For this reason, when we attempt to post a grade the call fails. I have search all over and have not been able to figure out the cause of this. I have seen this across clients so it does not seem to be specific to a single client of ours.
Any help would be much appreciated.
Also this is an LTI 1.0/1.1 tool.
Thanks!
