Why am i getting this: 'Exception occured while processing the request.'

[gigimatto88]

When i query firebase with:

var resp = await App.Database._firebase
              .Child("Users")
              .Child("jhon")
              .OnceAsync<User>();

i get this exception:

Firebase.Database.FirebaseException: 'Exception occured while processing the request. Url: https://test-70a12-default-rtdb.firebaseio.com/Users/jhon/.json Request Data: Response: {"CreationDate":"2021-01-19T11:32:18.183198+01:00", "Name":"jhonatan", "ID":"-MRPBwk2CgZYYmWZ5eFd","RegistrationCompleted":false,"ScoreLeft":10,"ScoreTotal":0}'

This is my firebase:

{
  "Users" : {
    "jhon" : {
      "CreationDate" : "2021-01-19T11:32:18.183198+01:00",
      "Name" : "jhonatan",
      "ID" : "-MRPBwk2CgZYYmWZ5eFd",
      "RegistrationCompleted" : false,
      "ScoreLeft" : 10,
      "ScoreTotal" : 0
    }
  }
}

This is my User model:

using System;
using System.Collections.Generic;
using System.Text;
using Xamarin.Essentials;
using System.Runtime.Serialization;
using System.Collections.ObjectModel;
using Newtonsoft.Json;

namespace test.Models
{
    [DataContract]
    public class User
    {
        [JsonProperty("ID")]
        public string ID { get; set; }

        [JsonProperty("Name")]
        public string Name { get; set; }

        [JsonProperty("CreationDate")]
        public DateTime CreationDate { get; set; }

        [JsonProperty("ScoreTotal")]
        public int ScoreTotal { get; set; } = 0;

        [JsonProperty("ScoreLeft")]
        public int ScoreLeft { get; set; } = 10;

        [JsonProperty("RegistrationCompleted")]
        public bool RegistrationCompleted { get; set; } = false;
    }
}

It seems to me a deserialization error but i can't figure out why.

[Astromarina]

I have exactly the same issue. reproducible with package versions 4.0.3, 4.0.4, 4.0.5 (Jan 19, 2021)

looks like Google changed something so that old code does not work any more

[LeoJHarris]

Also getting an exception similar to this which I believe is deserialization error which no longer allows me to call the API's on the Firebase.Database library... Error converting value False to type 'MyApp.Business.Person'. How it this even possible?

My Method looks like this:

public async Task<Person?> GetPersonAsync(string uid)
        {
            FirebaseObject<Person> person = (await _firebaseClient
              .Child(nameof(Person))
              .OnceAsync<Person>().ConfigureAwait(false)).SingleOrDefault(person => person.Object.UserInfo.Uid == uid);

            return person.Object;
        }

@bezysoftware is this something that can be looked into? The current implementation for querying firebase database doesn't work at all. I rolled back my code from a few months ago about last year when my code was definitely working fine and the same issue was reproduced when I tried to query database on firebase. I think something in the deserialization process is throwing an exception perhaps how firebase now returns data on its API's but for the last few months this has not worked at all.

I am happy to provide what's needed to help resolve this but from the above previous comment the stack trace is providing a clue to the deserialization, I can also note that I added this package directly to my project and also the Newtonsoft.Json project and there was definitely an issue on the deserialization in the Newtonsoft.Json. Its worth what is being returned from firebase API's and see if anything has changed.

[LeoJHarris]

@Astromarina

looks like Google changed something so that old code does not work any more

Do you have a link to this somewhere? Keen to know what changed.

As a side not this issue is reproducible on every version not just those you mentioned.

[LeoJHarris]

Hi @bezysoftware final call from us if this issue will be looked at before we look into shifting to an alternative to firebase.

[bezysoftware]

Can't you use Oncesingleasync to access a single object?

@bezysoftware thanks for getting back to me. I can confirm that OnceSingleAsync does not work same as OnceSingle. I'm willing to bet as @Astromarina mentioned that Google changed something and these API's now longer work.

To summarise I tried the following code

var all = await _firebaseClient.Child(nameof(Person)).OnceSingleAsync<Person>().ConfigureAwait(false);

And got the following (omitted some sensative data)

Resolved pending breakpoint at '/Users/TestAppServices/FirebaseService.cs:202,1' to void TestApp.Services.FirebaseService.<GetPersonAsync>d__14.MoveNext () [0x000d9].

but looks like some serialisation issues occurring in Newtonsoft.Json:

Newtonsoft.Json.JsonSerializationException: Error converting value "" to type 'TestApp.Types.LoginType'. Path 'LoginType', line 1, position 167. ---> System.ArgumentException: Must specify valid information for parsing in the string.

[bezysoftware]

I think the error is pretty self-explanatory:

Error converting value "" to type 'TestApp.Types.LoginType'. Path 'LoginType', line 1, position 167.

The library is using Newtonsoft.Json which is not able to deserialize empty string into LoginType.

See e.g. https://stackoverflow.com/questions/20104575/how-to-handle-deserialization-of-empty-string-into-enum-in-json-net

It's possible google was returning empty values as nulls, but now it returns actually empty string? Dunno
