Error 400 - Bad Request an Creating user with Microsoft Graph

I am trying to create a new user in my tenant using Microsoft Graph (v1.0) with help of the Microsoft doc.
When I create my user, I always get an error 400 bad request as response.

I am using HttpClient to make the post Request.

My Function :

private async Task<string> BuildUser(string token, string query)
    {
        httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
        UserCreation uc = new UserCreation
        {
            accountEnabled = this.checkBoxActive.Checked,
            displayName = this.textBoxDN.Text,
            mailNickName = this.textBoxMail.Text,
            passwordProfile = new PasswordProfile { forceChangePasswordNextSignIn = this.checkBoxChangeMDP.Checked, password = this.textBoxPassword.Text},
            userPrincipalName = this.textBoxUPN.Text
        };

        string json = JsonConvert.SerializeObject(uc);
        var content = new StringContent(json, Encoding.UTF8, "application/json");
        HttpResponseMessage response = httpClient.PostAsync(query, content).Result;
        return response.ToString();
    }

My token is valid and i am able to make simple Get requests, my app have the authorizations mentioned here.

For example, my json var can contains :

{
    "accountEnabled":true,
    "displayName":"cyril testgraphh",
    "mailNickName":"cyriltestgraphh",
    "userPrincipalName":"[email protected]",
    "passwordProfile":{
        "forceChangePasswordNextSignIn":true,
        "password":"XXX"
    }
}

EDIT : I solved my problem by using Microsoft Graph objects (Microsoft.Graph.User and Microsoft.Graph.PasswordProfile) and add .onmicrosoft.com to my upn

In my case the only thing returned from Azure Graph API was the error 400 - Bad Request... nothing else. :(

What I did to solve it? I was using the full blown Group object from Microsoft.Graph NuGet package to create a Group on Azure B2C. However, I was just using 5 properties of that object. While serializing to JSON it was serializing all properties of that class and for some reason the Graph API was barking about a malformed request.

So I just created an anonymous type with the properties that I needed:

var group = new
{
    DisplayName = theGroupName,
    Description = $"User group for {theGroupName}",
    MailNickname = theGroupName.Replace(" ", string.Empty),
    MailEnabled = false,
    SecurityEnabled = true
};

After sending this streamlined object to the Graph API endpoint, I got a success response.

You should check your code. I tried the following code, it works well.

using Microsoft.Graph;
using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Text;
using System.Threading.Tasks;
 
namespace ConsoleApp4
{
    class Program
    {
        static void Main(string[] args)
        {
            HttpClient httpClient = new HttpClient();
            httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
            UserCreation uc = new UserCreation
            {
                accountEnabled = true,
                displayName = "cyril testgraphh",
                mailNickName = "cyriltestgraphh",
                passwordProfile = new PasswordProfile { ForceChangePasswordNextSignIn = false, Password = "Password!" },
                userPrincipalName = "[email protected]"
            };
 
            string json = JsonConvert.SerializeObject(uc);
            var content = new StringContent(json, Encoding.UTF8, "application/json");
 
            HttpResponseMessage response = httpClient.PostAsync("https://graph.microsoft.com/v1.0/users", content).Result;
            Console.Write(response);
            Console.ReadLine();
        }
    }
    class UserCreation
    {
        public bool accountEnabled { get; internal set; }
        public string displayName { get; internal set; }
        public string mailNickName { get; internal set; }
        public string userPrincipalName { get; internal set; }
        public PasswordProfile passwordProfile { get; internal set; }
    }
 
}

And the response like this:
