So i am using the latest codeigniter 4, I am trying to edit/ update user information. however its just running me in a loop for the first check.

What I am trying to do is check if the data has changed, if it has not validate and save the new information if there is a problem return with validation errors.

However when adding

    if (!$user->hasChanged()) {
        return redirect()->back()
            ->with("message", "Nothing to update.");
    }

to the mix if i change the username it does not update it just gives message nothing to update

public function update($id)
{

    $users = auth()->getProvider();
    $user = $users->findById($id);

    $validation = ConfigServices::validation();
    $validation->setRules([
        'username' => 'required|is_unique[users.username]',
        'email' => 'required|is_unique[auth_identities.secret]'
    ]);

    $data = [
        'username' => $this->request->getPost('username'),
        'email' => $this->request->getPost('email')
    ];

    if (!$user->hasChanged()) {
        return redirect()->back()
            ->with("message", "Nothing to update.");
    }

    if ($validation->run($data)) {

        $user->fill([
            'username' => $data['username'],
            'email' => $data['email']
        ]);

        $users->update($user);

         return redirect()->to("admin/dashboard/manage-users")
                ->with("message", "User updated.");

    }
     return redirect()->back()
            ->with('errors', $validation->getErrors())
            ->withInput();
}
