Queries from Firebase not working

I’ve been working on a game where one of the features is that you can sell a skin on a marketplace, just like steam.
The problem is, the query code that I’ve been using just returns “0” to every variable and the result state is “ok”.
I didn’t have any of these problems when using get documents, but then I would have problems getting even 2 sellers because you can’t have the same document name and when searching for the document using gdevelop the name has to be exactly the same. It can’t have any other letter or number in it.

This is the code I am currently using.
