Getting error when click on Publish under Team schedule via Line Manager

Summary: I am getting the error (An error prevented the schedule from being published. Try publishing again and if the problem persists, contact your help desk.) when I click on Publish button from Action drop-down under Quick Action>Team schedule via Line manager. My custom line manager role has below privileges added already:

Manage Planned Schedule

Manage Scheduler Profiles

Manage Team Schedule

View Published Schedule

However, when I add Time and Labour manager role to my test user, I don't get the error. I am not sure which privileges/duty role is there in the seeded Time and Labour Manager role as I have added the ones with keyword 'schedule', 'publish' , 'Team' etc
