After upgrade, the On-Call Schedules UI page is not loading.
Rosters hold reference to users who no longer exist in the sys_user table.
Existing rosters in active Shifts have invalid roster members. In the 'Members' related list found on the roster record, there are members with the Name value displaying as 'Empty'. The sys_id for these users cannot be found in the User (sys_user) table. The invalid users will need to be removed from active rosters.
