Banner to Canvas Update Error

Community Novice

Yesterday, beginning late afternoon, the Canvas import “disappeared” our courses with invalid sub-accounts rather than attaching them to the root account.

This is an example of the error message from the course import (below) .  We had 221 courses get “disappeared” yesterday, and they all had an error message like this one.

Account not found "AC" for course AC223A202050

Did anyone else experience this issue?
