I am struggling to integrate Canvas with IMathAS using a developer key.
When I access the assignment imported from IMathAS in Canvas, I encounter 2 types of errors.
- Invalid token error
request type: GET
request URL: https://canvas.instructure.com/post_message_forwarding?rev=59677caad5-09bb3c9388a5ba3a&token=eyJ0eXA...
response code: 403 Forbidden
response message: Invalid token
- Invalid lti_message_hint
request type: GET
request URL: https://sso.canvaslms.com/api/lti/authorize_redirect?scope=openid&response_type=id_token&response_mo...
response code: 400 Bad Request
response message: {status: "bad_request", message: "Invalid lti_message_hint"}
I've correctly set the Developer Key(LTI key) and the Client ID according to the instructions.
Can you instruct me how to solve these issues?
