Bad request: Invalid lti_message_hint #33

Receiving an "Invalid lti_message_hint" error after being forced to open a new tab.

Gonna need more info if you want help. For starters, which LMS are you using that's giving you this error?

That's my bad @chrispittman ! Canvas LMS. I actually got it to work after using the direct authorize location (from https://canvas.instructure.com/api/lti/authorize_redirect to canvas.{{domain}}).
