VBS How to Map REST Dynamic Parameters to optional tags

Summary:

Hi,

At the moment we try to build a web apps in VBS to acomplish a customer requirements, some REST Services have a dynamic parameters, when I test the service connection, it is successful with differents dynamic parameters filled, but when put the same information in the exposed fields, the REST Service doesn't show results if not all the dynamic parameter are filled, I think the problem is in the map of variable or in the input parametes map in the "call rest" step in the action chain that I use with the button.

how we should be map the dynamic parameters to send to the rest connection only the filled information?
