OperationResponse 230: ReturnCode: 32755 (Custom authentication deserialization failed: Unexpected C

I have created a simple PHP login system integrated into PUN (Custom Authentication)

Here is my code within the game:

    public class DBTest : MonoBehaviourPunCallbacks  
        {  
            public TMP_InputField txtUsername, txtPassword;  
            public Button btnSubmit;

        [SerializeField]  
        private TMP_Text lblStat;

        public string player_username;  
        public string player_password;

        public void SignInButton()  
        {  
            player_username = txtUsername.text;  
            player_password = txtPassword.text;

            PhotonNetwork.AuthValues = new AuthenticationValues();  
            PhotonNetwork.AuthValues.AuthType = CustomAuthenticationType.Custom;

            //BE SURE THAT THE FIRST VAR IN THE AUTH PARAMETER IS THE SAME WITH THE VAR NAME IN THE PHP FILE!  
            // e.g. "player_username"  
            PhotonNetwork.AuthValues.AddAuthParameter("player_username", player_username);  
            PhotonNetwork.AuthValues.AddAuthParameter("player_password", player_password);  
            PhotonNetwork.ConnectUsingSettings();  
        }

        public override void OnJoinedLobby()  
        {  
            base.OnJoinedLobby();  
            Debug.Log("Success");  
        }


        public override void OnCustomAuthenticationFailed(string debugMessage)  
        {  
            base.OnCustomAuthenticationFailed(debugMessage);  
            Debug.Log(debugMessage);  
        }


    } //End: Class

 1,  
        "Message" => "Success",  
        );

        //Pass json  
        $json_success = json_encode($login_success);  
        echo $json_success;  
        */  
          
        $loginresult = new stdClass();  
        $loginresult->ResultCode = 1;  
        $loginresult->UserId = $player_username;  
          
        $jsonresult = json_encode($loginresult);  
        echo $jsonresult;  
    }  
    else  
    {  
        /*  
        //User doesnt match  
        //Create array result  
        $login_fail = array (  
        "ResultCode" => 2,  
        "Message" => "Failed",  
        );

        //Pass json  
        $json_fail = json_encode($login_fail);  
        echo $json_fail;  
        */  
          
        $loginresult = new stdClass();  
        $loginresult->ResultCode = 2;  
        //$loginresult->message = "failed";  
          
        $jsonresult = json_encode($loginresult);  
        echo $jsonresult;  
    }  
      
    /*  
    echo "

";  
    echo $player_username;  
    echo "
";  
    echo $player_password;  
    echo "
";  
    echo $count;  
    */

?>

I also tried creating a separate php file to test if my initial php connector works, and it did. Here is the dummy php file:

How can I solve this? I'm really stuck at this point. I tried googling but got no decent answer (rarely does a custom authentication tutorial for pun exists) so I really got nothing.

Anything that might help me solve this is much appreciated.

Hi @DKReigns,

Make sure the returned response from the server is a valid JSON string.

Forgive me for being naive, but how can I achieve something like that?

My PHP knowledge is very basic.

Maybe the PHP script is returning something before this line

    if($count == 1)  

Check if you have other echo calls somewhere.
Probably something that starts with "C" (hint in the error message) maybe "Connection"?
Check "connection.php" or maybe an error/exception is thrown in

    $result = mysqli_query($connection, $sql);  

    $count = mysqli_num_rows($result);

Thanks! It was on my connection.php where I placed a debug message that says 'echo "Connection Successful!"

I managed to get it working now.

One more question though, how can I get the returned parameters from the server?
As of the moment, I only use Debug.log to display a "successful" message once I got connected to the server. I want to get the returned value from the server, namely the 'UserId'

I have:

$loginresult = new stdClass();
$loginresult->ResultCode = 1;
$loginresult->UserId = $player_username;
$loginresult->message = "Login Successful!";

    $jsonresult = json_encode($loginresult);  
    echo $jsonresult;</code>

    }</code>

    $jsonresult = json_encode($loginresult);  
    echo $jsonresult;</code>
