LTI readResultRequest is returning a null response

Hello,

 

We're trying to integrate an existing LTI tool with Blackboard, and we're unable to have grades properly recognized by the AMI Blackboard instance. When we try with either our connector, or with a test tool provider (IMS LTI tool provider emulator) any update to the gradebook responds with a NULL response each time.

 

For tool provider creation, we're using System Admin -> LTI Tool Providers -> Register Provider Domain (with url, key, secret) -> Manage placements. We've also enabled grades and are accessing this through a learner (so we have a valid lis_result_sourcedid and lis_outcome_service_url). We're comfortable using a different method to setup the LTI placement, but we just need to have grades recognized. Additionally, if there's any additional documentation / debugging steps for setting up the gradebook connection, I'd appreciate it.

 

Please let me know if I need to provide more information.

 

Thanks!
