Hello!
I try to integrate my simple frontend app with LTI.
This is my login response on OIDC POST:
{
"scope": "openid",
"response_type": "id_token",
"client_id": "my_id",
"redirect_uri": "https://lovely-liger-13.loca.lt/project/submit",
"login_hint": "2",
"state": "DFY7YkpCMGF16Y5by32CsT7MNhJjO8",
"response_mode": "form_post",
"nonce": "DJe0Ld2hr70CgFkHOWaHeeqRN",
"prompt": "none",
"lti_message_hint": "25"
}
My configuration at Moodle side:
Tool Url: https://lovely-liger-13.loca.lt
Public key type: RSA with key provided in the following format:
-----BEGIN PUBLIC KEY-----
PbhHpvY3V7+gLFPFOjMOy8DJ6rig5jimokHu9zxmTiLtHvpdMCAwEAAQ==...
-----END PUBLIC KEY-----
Initiate login URL: https://lovely-liger-13.loca.lt/oidc
Redirection URL(s): https://lovely-liger-13.loca.lt/project/submit
When I try to initiate Launch I get 400 on /project/submit with:
{"error":"invalid_request","errors":["Login Response was rejected: invalid_request"]}How can I investigate it further? Are there some params missing?
