Save and Restore Lists not working!

[c-q-f]

Hi there!

// I can save a list do database: async static void Save() { var myColl = new List(); myColl.Add(new Person { ID = 1, Name = "Peter" }); myColl.Add(new Person { ID = 2, Name = "Paul" }); myColl.Add(new Person { ID = 3, Name = "Mary" });

        FirebaseClient firebase = new FirebaseClient("https://xxxxxxxxxxxx.firebaseio.com/");
        await firebase.Child("MyApp").Child("Clients").PutAsync<List<Person>>(myColl);
    }

// but I can't restore it (an exception rises): async static void Restore() { FirebaseClient firebase = new FirebaseClient("https://xxxxxxxxxxxx.firebaseio.com/"); var myColl = await firebase.Child("MyApp").Child("Clients").OnceAsync<List>(); }

EXCEPTION: Firebase.Database.FirebaseException HResult=0x80131500 Message=Exception occured while processing the request.

This exception was originally thrown at this call stack: Newtonsoft.Json.Serialization.JsonSerializerInternalReader.EnsureArrayContract(Newtonsoft.Json.JsonReader, System.Type, Newtonsoft.Json.Serialization.JsonContract) Newtonsoft.Json.Serialization.JsonSerializerInternalReader.CreateList(Newtonsoft.Json.JsonReader, System.Type, Newtonsoft.Json.Serialization.JsonContract, Newtonsoft.Json.Serialization.JsonProperty, object, string) Newtonsoft.Json.Serialization.JsonSerializerInternalReader.Deserialize(Newtonsoft.Json.JsonReader, System.Type, bool) Newtonsoft.Json.JsonSerializer.DeserializeInternal(Newtonsoft.Json.JsonReader, System.Type) Newtonsoft.Json.JsonSerializer.Deserialize(Newtonsoft.Json.JsonReader, System.Type) Newtonsoft.Json.JsonConvert.DeserializeObject(string, System.Type, Newtonsoft.Json.JsonSerializerSettings) Newtonsoft.Json.JsonConvert.DeserializeObject(string, Newtonsoft.Json.JsonSerializerSettings) Firebase.Database.Http.HttpClientExtensions.GetObjectCollectionAsync(System.Net.Http.HttpClient, string, Newtonsoft.Json.JsonSerializerSettings)

Inner Exception 1: JsonSerializationException: Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'System.Collections.Generic.Dictionary2[System.String,System.Collections.Generic.List1[ConsoleApp1.Person]]' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly. To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array. Path '', line 1, position 1.

If you want to be using arrays instead of standard dictionaries, try OnceSingleAsync
