I had the same problem and decided to check if all properties are setting my local object. Just validating if the property is null, did not resolve.

Before:

var item = await firebase.Child("users").OnceAsync <Users> ());

Then:

using Newtonsoft.Json.Linq;

var item = await firebase.Child("users").OnceAsync <JObject> ());

The problem is in the deserialization. You can access the properties in the JObject with:

var itemProperty = item.Object.GetValue("<property_name>").
