[ARCHIVED] LTI 1.3 Tool does not have permission to view line_item

[glenn_oslin]

For some reason my tool is not able to "view" some of the line items in a course. Any idea how to fix it?

Here are the details.

We work with several schools, but North Missouri started having this issue FOR SOME STUDENTS.

If you decode the id_token you can see the default item is

https://nwmissouri.instructure.com/api/lti/courses/31079/line_items/638

However when I GET it I get this

I can access other ids though.

And I can list the line_items as well, but /638 is not in the list.

This is definitely a permissions issue but strikes me as very weird that only some students have the issue. Why?

The scopes looks correct too (Again, without the scope I shouldn't be able to access the line items)

Here's the JWT
