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.
