How to test if an output exists in previous step

How can I determine which values are available for use in subsequent workflow steps when the MySQL step in Pabbly returns variable outputs? Specifically, I'm looking to distinguish between the presence of the requested records or the the response that no records were found. Both situations return "status" of "success", and a second element - either "results" or "message" How do I test which condition I have without causing an error condition?

You need to use Filter Action by Pabbly Connect you can use Exist filter.
