Hi, I tried to use drupal's blocks through LTI on other LMS (open edX). But getting error "The used authentication method is not allowed on this route"
1. Generate security credentials (admin/config/lti-tool-provider/consumer, Name field - user_id, Mail field - lis_person_contact_email_primary) and set it's to LTI consumer block on LMS.
2. Create test module url (/en/group/4/module/4/answer/2) and set in LMS.
3. Try to use it on LMS side from test user
LMS says to test user:
You are not authorized to access this page.
LTI consumers block (on my LMS) sends to Drupal some data:

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Same error. This is very hard to troubleshoot, as the exception does not have a message and it is not clear from the stacktrace what is causing it.
I was getting this error on every page of a site. I fixed it by uninstalling basic_auth module using Drush.
