Save button throws error message for mandatory fields. User has a flow action which has some mandatory fields in their deployment. User decides to close the assignment without input of any data and clicks on the Save button. This action throws errors for the mandatory fields. Ideally it must not validate for the mandatory fields in case of Save.
