Comment corriger l'error org.json.JSONException: End of input at character 0 of

Bonjour les experts,

Je suis nouveau sur Androïd et je suis entrain de réaliser TP de Login via un serveur web PHP/MYsql en utilisant la library Volley, et voilà, lors de ma tentative de connexion j'ai ce message d'erreur: error org.json.JSONException: End of input at character 0 of

C'est simplement le tuto suivant: https://www.youtube.com/watch?v=yS5n40h4Wlg

Votre aide me serait très précieuse, merci d'avance
Voici mon LoginActivity.class

public class LoginActivity extends AppCompatActivity {
    private EditText email, password;
    private Button btn_login;
    private TextView link_regist;
    private ProgressBar loading;
    private static String URL_LOGIN = "http://xxx.com/login.php";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);

        loading = findViewById(R.id.loading);
        email = findViewById(R.id.email);
        password = findViewById(R.id.password);
        btn_login = findViewById(R.id.btn_login);
        link_regist = findViewById(R.id.link_regist);

        btn_login.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String mEmail = email.getText().toString().trim();
                String mPass = password.getText().toString().trim();

                if(!mEmail.isEmpty() || !mPass.isEmpty()){
                    Login(mEmail, mPass);
                }else{
                    email.setError("Please insert Email");
                    password.setError("Please insert Password");
                }
            }
        });

        link_regist.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                startActivity(new Intent(LoginActivity.this, RegisterActivity.class));
            }
        });
    }

    private void Login(final String email, final String password) {
        loading.setVisibility(View.VISIBLE);
        btn_login.setVisibility(View.GONE);

        StringRequest stringRequest = new StringRequest(Request.Method.POST, URL_LOGIN,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        try {
                            JSONObject jsonObject = new JSONObject(response);
                            String success = jsonObject.getString("success");
                            JSONArray jsonArray = jsonObject.getJSONArray("login");

                            if(success.equals("1")){
                                for (int i = 0; i < jsonArray.length(); i++){

                                    JSONObject object = jsonArray.getJSONObject(i);

                                    String name = object.getString("name").trim();
                                    String email = object.getString("email").trim();

                                    Toast.makeText(LoginActivity.this,
                                            "Success Login. \nYour Name :"
                                                    +name+" \nYour Email :"
                                                    +email, Toast.LENGTH_SHORT)
                                            .show();
                                    loading.setVisibility(View.GONE);
                                }
                            }
                        } catch (JSONException e) {
                            e.printStackTrace();
                            loading.setVisibility(View.GONE);
                            btn_login.setVisibility(View.VISIBLE);
                            Toast.makeText(LoginActivity.this, "Error " +e.toString(), Toast.LENGTH_SHORT).show();
                        }
                    }
                },
                new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                        loading.setVisibility(View.GONE);
                        btn_login.setVisibility(View.VISIBLE);
                        Toast.makeText(LoginActivity.this, "Error " +error.toString(), Toast.LENGTH_SHORT).show();
                    }
                })
        {
            @Override
            protected Map<String, String> getParams() throws AuthFailureError{
                Map<String, String> params = new HashMap<>();
                params.put("email", email);
                params.put("password", password);
                return params;
            }
        };

        RequestQueue requestQueue = Volley.newRequestQueue(this);
        requestQueue.add(stringRequest);
    }
}

Et maintenant, voici mon script PHP de login

<?php

if ($_SERVER['REQUEST_METHOD']=='POST') {

    $email = $_POST['email'];
    $password = $_POST['password'];

    require_once 'connect.php';

    $sql = "SELECT * FROM users_table WHERE email='$email' ";

    $response = mysqli_query($conn, $sql);

    $result = array();
    $result['login'] = array();
    
    if ( mysqli_num_rows($response) === 1 ) {
        
        $row = mysqli_fetch_assoc($response);

        if ( password_verify($password, $row['password']) ) {
            
            $index['name'] = $row['name'];
            $index['email'] = $row['email'];
            $index['id'] = $row['id'];

            array_push($result['login'], $index);

            $result['success'] = "1";
            $result['message'] = "success";
            echo json_encode($result);

            mysqli_close($conn);

        } else {

            $result['success'] = "0";
            $result['message'] = "error";
            echo json_encode($result);

            mysqli_close($conn);

        }

    }

}

?>
