Hello, I have a similar query. In calling the /register endpoint I’m getting
{“error”:“invalid_request”,“error_description”:“Failed to parse and validate request JWT: bad_request.unknown_kid: Signature with unknown key”,“error_params”:{“original_error_code”:“bad_request.JWT”}}
But I’m sure the Key Id and certificate is our one registered with the Directory Sandbox. Is there anything else I need to register with you before running the client registration request?
