Thanks @mohdali , may I know why this would fix #4818 ? I have set the interval for the timer in the Studio, seems the default value will not be used.

The default value of null will cause Quartz scheduler to fail to start. Currently Elsa studio upates the value on change only. So even if you manually edit the value but kept it as 00:01:00 it will still be treated as null.

Otherwise, Quartz scheduling should work just fine.
