Grade Passback Warning Message

This forum has a limit to the number of forum postings you can make in a given time period - this is currently set at 10 posting(s) in 1 day

Using Brightspace LTI 1.3 and WW 2.19.

At the time that the LTI is set to do a mass grade update, both the instructor and the students are seeing this warning message pop up wherever they are within WW (a homework set, a homework problem, etc). It goes away quickly, once the update occurs, but it is rather annoying.

The grades are being passed back to Brightspace just fine for the students. Although for the professor, the log is showing a message like:

Submitting grade for user instructor and set Section_02.2.
Using current access token from database.
Found data required for submitting grades to LMS.
Failed to send grade: UnprocessableEntity

The warning message also appears every time the instructor manually triggers a LTI Grade Update.

Is this just something to expect with 2.19? Or is there something I am missing?

Most LMS's do not provide grade passback for instructors, and that is why the warnings are occuring. That was true for LTI 1.1 and for previous versions of WeBWorK as well.

However, the warnings should not show up in the browser unless you have debugging turned on. Check that you have $debug_lti_grade_passback = 0 in conf/authen_LTI.conf.
