I work for a vendor attempting to integrate our platform with Buzz via LTI 1.3. We've successfully integrated all aspects except deep linking which provides us with the following error message:
Process Deep Linking Response Message
Response message does not contain required data.
Our integration works well with other LMS platforms (we've got clients using Canvas and Moodle with LTI 1.3 so far), so I was wondering what data we're missing that is required for LTI 1.3 deep linking with Buzz?
