WordPress CPL using JWT Token return error

Question

I have to validate the users through 2 processes. This is the first: If a valid token is returned I move on to phase 2, which is just pulling a Customers List and then correlating the username. To get the customer's ID etc. and then save it to the local storage to persist the user and allow for Simpler Order Send outs.

The Error:

Unexpected character encountered while parsing value: <. Path '', line 0, position 0.'

The Error is vague as all hell And I have no idea what the problem is here.

  class WpApiCredentials
    {
        public static string SiteUri = "http://TheSite.co.za/";
        public static string WordPressUri = $"https://public-api.wordpress.com/wp/v2/sites/{SiteUri}/";
        public static string Username = "Name";
        public static string Password = "password";
    }


 WpApiCredentials.Username = Usernamelabel.Text;
 WpApiCredentials.Password = PasswordLabel.Text;


var client = new WordPressClient(WpApiCredentials.SiteUri);
client.AuthMethod = AuthMethod.JWT;
await client.RequestJWToken(WpApiCredentials.Username, WpApiCredentials.Password);

       
 var isValidToken = await client.IsValidJWToken();

 if (isValidToken)
            {

             await App.Current.MainPage.DisplayAlert("Token Received", "Phase 1 is done ", "OK");
             Login_Phase2();
                   
            }
            else
            {
                await App.Current.MainPage.DisplayAlert("Empty Values", "Token not Found", "OK");
            }

Here's what I can find in regards to the RequestJWToken Task

        [AsyncStateMachine(typeof(<RequestJWToken>d__29))]
        public Task RequestJWToken(string Username, string Password);

[Obsolete("Use JWT instead of Basic")]
        Basic,

Found the Method

public async Task RequestJWToken(string Username, string Password)

            var route = $"{_jwtPath}token";
            var formContent = new FormUrlEncodedContent(new[]

                    new KeyValuePair<string, string>("password", Password)

            (JWTUser jwtUser, HttpResponseMessage response) = await _httpHelper.PostRequest<JWTUser>(route, formContent, false).ConfigureAwait(false);
            //JWToken = jwtUser?.Token;
            _httpHelper.JWToken = jwtUser?.Token;
        }

Answer 1

It Ended up being something Extremely Stupid

If you notice public static string SiteUri = "http://TheSite.co.za/"; Doesnt have /wp-json at the end.

So Method ended up being

something like this

 var client = new WordPressClient("http://Your-Site/wp-json/");
            client.AuthMethod = AuthMethod.JWT;
            await client.RequestJWToken(TheUserName, ThePassword);

            var x = client;
            var isValidToken = await client.IsValidJWToken();



            WpApiCredentials.token = client.GetToken();

            if (isValidToken)
            {

                Login_Phase2();
            }
            else
            {

                await App.Current.MainPage.DisplayAlert("Empty Values", "Token not Found", "OK");
            }
