Issue executing search request with parameters using C# Kveer.XmlRPC. I can't understand what version of API I'm using, and I think that this can be a reason of issue. The proplem is reproducible only when I add 3 values("is_company", "=", true) in nested object of _params variable. In addition to this method, I have tried many for example set them as one value etc but I still receive errors. This is most common way people set parameters in this request(I get this from most different sources). So how to correctly set parameters? What I do wrong? Is it possible the api version can be reason of error?
