As per your console logs, i can see there’s an access permission problem.
Just double check the access rights for the following ‘MyFirstModule.Global_Calendar_Info ’ involved entity/page/microflow’s, whether the respected user roles got assigned or not.
The user who exececutes the DB query doesn't have sufficient access rights to the queried Entity.
”MyFirstModule.Global_Calendar_Info failed for security reason”
Check your access rule for the involved user role and if a microflow involved if security is enable or not
