I have one problem with Assignments where a tutor going to mark submitted work is given and error
Can not find data record in database table oauth2_issuer.
I can't figure out why it's throwing up this error. Any pointers would be very gratefully received.
I've added a screenshot for info, as you'll see submitted work is there but when they click the grade button - the error comes up.
Moodle version is 3.6.2
