Grades via LTI 1.0 are not getting into the Moodle gradebook

[Kristina Hoeppner]

When the external LTI tool is set up to push grades for a portfolio to Moodle, the grade never arrives in Moodle. It is only displayed in Mahara.

To test in Mahara 20.10 (21.04 doesn't display the grade option, but I suspect it has the same issue; separate bug #1941663)

1. Set up the portfolio submission to Moodle as described in the manual: https://manual.mahara.org/en/20.10/external/externalapps.html
2. Submit a portfolio as a student coming from Moodle.
3. Grade the portfolio in Mahara as a teacher. The grade is displayed.

Expected result: The grade is also displayed in the Moodle gradebook.
Actual result: It is not displayed, not even waiting a few minutes in case a cron needed to run first.

When you go to the web services logs in Mahara, you see the attached:

Even though the web services user is in an institution, it says 'root' and there is no mention of an institution. The error message is "exception: WebserviceAccessException message: Access control exception : Invalid token selected or none supplied debuginfo: "

Interestingly, the grade is pushed to Canvas. It just seems that Moodle is having a problem.

This problem is fixed with bug #1941663 as far as I can see.
