Different responses for Query

Question

I do have a RestAPI call which is going to list all servers defined in our environment. Because of different use cases the RestAPI call will not always return the same amount of attributes.

The problem I am facing now is that now all values are going to be returned every time. Therefore I need a method to declare which one I expect to be present all time.

I have tried the * match contains but without success

How can I do this?
