If you do not need to pass the parm2 parameter in the Event Details section of the Workflow Activity record, what is the default method passed in?

In the context of ServiceNow and particularly within a Workflow Activity record, when there is a need to specify a user parameter (like parm2) and it is not explicitly provided, the default method that is invoked is typically gs.getUserName(). This method retrieves the username of the currently logged-in user, making it a common fallback when specific user details need to be associated with workflow logic.

By contrast, the other methods serve different purposes. gs.getUserDisplayName() is intended to fetch the full display name of the user, which might not always be needed and is not the default method for user identification in this scenario. gs.getCurrentUser() returns a user object representing the currently logged-in user but does not directly provide the username. Lastly, gs.getCurrentUserId() returns the ID of the current user, which, while unique, is not typically used when a username is expected.

By using gs.getUserName() as the default, ServiceNow ensures that workflows can consistently reference the username, maintaining clarity and reducing the complexity associated with variable user identification within workflows.
