Azure B2C Graph API issue

Question

I am trying to run the sample at:

https://github.com/Azure-Samples/ms-identity-dotnetcore-b2c-account-management

And am receiving this error:

Enter command, then press ENTER: 7 Create a user with the custom attributes 'FavouriteSeason' (string) and 'LovesPets' (boolean) Have you created the custom attributes 'FavouriteSeason' (string) and 'LovesPets' (boolean) in your tenant?

Code: Request_BadRequest Message: One or more property values specified are invalid. Inner error: AdditionalData: date: 2020-06-30T23:24:26 request-id: dad23cee-984b-439c-a943-9e1bc6be4c9b ClientRequestId: dad23cee-984b-439c-a943-9e1bc6be4c9b

I have created the custom attributes and can clear see them in the tenant...it even returns their ids. I've setup the Graph access level appropriately (I believe).

Any ideas? Thank you!

In Code, you need to update Tenant id, client id, client secret and also give B2cExtensionAppClientId= “your application display name” in appsettings.json
You have to create two custom attributes in the B2C portal

I. FavouriteSeason (string)

II. LovesPets (boolean)

Use below code to create the user with the custom attribute

         try
         {
             //Create user
             var result = await graphClient.Users
             .Request()
             .AddAsync(new User
             {
                 GivenName = "Casey",
                 Surname = "Jensen",
                 DisplayName = "Casey Jensen",
                 Identities = new List<ObjectIdentity>
                 {
                     new ObjectIdentity()
                     {
                         SignInType = "emailAddress",
                         Issuer ="AADCxPb2c.onmicrosoft.com",


                         IssuerAssignedId = "x@AADCxPb2c.onmicrosoft.com",
                     }
                 },
                 PasswordProfile = new PasswordProfile()
                 {
                     Password = b2c_ms_graph.Helpers.PasswordHelper.GenerateNewPassword(4, 8, 4)
                 },
                 PasswordPolicies = "DisablePasswordExpiration",
                 AdditionalData = extensionInstance


             }) ;
             Console.WriteLine(result);
             string userId = result.Id;
             Console.WriteLine(result.Id);
             Console.WriteLine($"Created the new user. Now get the created user with object ID '{userId}'...");
