There are some common scheduled tasks errors that can only be resolved by the user.
Error 1:
If the user system date format and the scheduler date format are not in sync.
Solution:
Users can update the scheduler date format according to their system date format by going to File > Options > Scheduler.
Error 2:
The user entered an invalid login name and password.
Solution:
Users should update the valid system credentials in the 'Run As Credentials' window in the General tab under 'Create Scheduled Task.'
Error 3:
If a task is being created with a name that already exists in Aqua Data Studio task scheduler.
Solution:
Give a unique name for the scheduled task. A task with a name that already exists would not be valid.
