new user failed to login with username and password

I try to login with a new created user. But when I try to login it throw’s the error message.

So This is the login:

public function login()
  {
    // Check for POST
    if ($_SERVER['REQUEST_METHOD'] == 'POST') {

      echo ('hello');
      // Process form
      // Sanitize POST data
      $_POST = filter_input_array(INPUT_POST, FILTER_SANITIZE_STRING);

      // Init data
      $data = [
        'email' => trim($_POST['email']),
        'password' => trim($_POST['password']),
        'email_err' => '',
        'password_err' => '',
      ];

      // Validate Email
      if (empty($data['email'])) {
        $data['email_err'] = 'Pleae enter email';
      }

      // Validate Password
      if (empty($data['password'])) {

        $data['password_err'] = 'Please enter password';
      }

      // Check for user/email
      if ($this->userModel->findUserByEmail($data['email'])) {

        // User found
      } else {
        // User not found
        $data['email_err'] = 'No user found';
      }

      // Make sure errors are empty
      if (empty($data['email_err']) && empty($data['password_err'])) {
        // Validated
        // Check and set logged in user
        $loggedInUser = $this->userModel->login($data['email'], $data['password']);
       
        if ($loggedInUser) {

          echo $data['password'];
          echo $data['email'];



          // Create Session
          $this->createUserSession($loggedInUser);
        } else {
          $data['password_err'] = 'Password incorrect';

          $this->view('users/login', $data);
        }
      } else {
        // Load view with errors
        $this->view('users/login', $data);
      }
    } else {
      // Init data
      $data = [
        'email' => '',
        'password' => '',
        'email_err' => '',
        'password_err' => '',
      ];

      // Load view
      $this->view('users/login', $data);
    }
  }

and so it doesn’t reach the two echo messages.

But I can’t figure out why I can’t login.

and the new created user is appearing in the database.
