Whenever I update the course settings for a class and click to save the changes, I'm getting this error message:
Exception - Argument 1 passed to local_o365\feature\usergroups\coursegroups::__construct() must be an instance of local_o365\rest\unified, boolean given, called in [dirroot]/local/o365/classes/observers.php on line 621
Based on that message, it seems to be an issue with groups, I'm guessing. I'm not actually using groups in the class. The settings are:
Group mode - No groups
Force group mode - No
Default grouping - None
This seems to have only popped up since updating to Moodle 3.10.3. I have the latest version installed (3.10.1 (2020110901)). Any ideas on what's causing this error?
