Cannot use variables in GET requests

Ok. It works after reimporting the data file. But there’s still a problem; it creates requests even when the agent_id is empty. Is it possible to set conditions on the requests (drop request is variable value if null/empty)?

E.g:

{
    "url": "http://localhost:3000/users/",
    "gadget_id": "",
    "user_id": "9d788283-87a9-4c38-8d48-30ddc1604058"
},

Don’t make request for gadget_id like

www.url.com/gadgets/{{gadget_id}}

gadget_id is empty so don’t even make the request.

Something like this:
