Hello,
When I used a student moodle account, I get lis_result_sourcedid and lis_outcome_service_url. And tried to send the grade back to Moodle and it works. But, when I saved these lis_result_sourcedid and lis_outcome_service_url in our database and use again these for sending grade back to Moodle again then I am getting below error.
Can anyone please help with this?
