Canvas LTI 1.3 Error: login_required

Jump to solution

Hello all,

I'm attempting to implement IMS LTI 1.3 for a tool provider and I'm developing against a local canvas environment.

During the launch step, the authentication response canvas sends is as follows:

This is strange since I have prompt: none as one of the parameters I send during the OIDC initiation. There's one other post in this forum that encountered a similar issue here, but truth be told how the original poster was able to solve the problem was unclear. I did verify that I'm sending the same lti_message_hint and login_hint to canvas. Is this an issue with the local canvas environment I'm developing against? I went through the manual installation steps described here.

 

Any help is appreciated!

For me personally, the issue was in regards to the client_id. I had created a new developer key and forgotten to update the client_id. Whoops!
