Firesharp: An error occured while execute request. Path : 0/ , Method : PUT

Question

I am exploring Firebase Realtime Database (RTDB) with C#, and am trying out the Firesharp framework on a .NET console app. I have followed most online tutorials on getting started, but was not able to post any data to my RTDB. I am thrown this error at AddData().Wait():

System.AggregateException has been thrown

"One or more errors occurred. (An error occured while execute request. Path : 0/ , Method : PUT)"

My implementation is like so:

class Program
{
    static IFirebaseConfig config = new FirebaseConfig
    {
        AuthSecret="MY_AUTH_SECRET",
        BasePath="https://MY_APP.firebaseio.com/"
    };

    static IFirebaseClient client;

    static void Main(string[] args)
    {
        Console.WriteLine("Hello World!");
        client = new FireSharp.FirebaseClient(config);

        if (client != null)
        {
            Console.WriteLine("Connection established!");
            AddData().Wait(); //Crashed here with above error
        }
    }

    public static async Task AddData() 
    {
        var data = new Data
        {
            id = "Hello",
            text = "World"
        };

        SetResponse response = await client.SetAsync("0/", data);
        Data result = response.ResultAs<Data>();
    }
}

I am fairly new to C#. Where have I gone wrong?

I'm using VS on Mac, and hence not writing a form app to test instead.

Are you sure the client has permission to write to the database? By default nowadays no such permission is granted. — Frank van Puffelen, Apr 29 '19 at 14:08
@FrankvanPuffelen How do i check on this? This line `Console.WriteLine("Connection established!");` prints successfully, so I presume its connected. I have also checked the security rules on firebase console, and are set to public. — Koh, Apr 29 '19 at 14:45
@samthecodingman have tried that as well, but still throws the same error. — Koh, Apr 29 '19 at 14:46
Hmm...public read/write should be good enough. I'm not sure what's going wrong in that case, since the error message is rather vague. Is there any way you can see if there's a nested exception? — Frank van Puffelen, Apr 29 '19 at 15:07
@FrankvanPuffelen I have added the full log inside my question. See edit — Koh, Apr 29 '19 at 15:34
There seem to be lots of other error messages in there, about an assembly not loading, and an issue with parsing JSON. Did you search for those yet? — Frank van Puffelen, Apr 29 '19 at 15:39
@FrankvanPuffelen I do not quite understand where does all these json serialization errors originate from, i am barely getting started. About the assembly loading, what file are we talking about? — Koh, Apr 29 '19 at 15:45
this is the tutorial that i follow: https://www.youtube.com/watch?v=jZMwwZHJXJc&list=PLuv4McUMmyAbsNdfZ4rH_OyEM3P2MJS-F — Koh, Apr 29 '19 at 15:46
my problem was related to different version of newtonsoft dll... — DarioN1, May 09 '19 at 15:35

Ok, so the problem to this issue was that I had two Nuget packages installed, Firesharp and Firesharp.Serialization.JsonNet.

I removed Firesharp and then made amendments to my AddData() function, and it all worked.

public static async Task AddData() 
{
    var data = new Data
    {
        id = "Hello",
        text = "World"
    };

    SetResponse response = await client.SetTaskAsync("0", data); //Change to SetTaskAsync here
    Data result = response.ResultAs<Data>();
}
