frappe.exceptions.DoesNotExistError: Task TASK00019 not found

Hi @paul-100

The link of task #TASK00019 is present in the one of the record of the Time Log, but the TASK00019 is not exist in the system. So set the null value for the task in the time log which is not exist in the system using sql query.

Thanks, Rohit
