Inertia Js , React Problem To Handle Laravel Returned Errors

ok, I've been using inertiaJs for a little over 1 year, only it's as if inertia can no longer receive data from the backend.

for example, here's the simple authentification form I send:

const handleSubmit = (values) => {
    router.post(route('instance.login', { as: as }), values, {
      errorBag: “errors”,
      onStart: (visit) => {
        setLoading(true);
      },
      onSuccess: (successful) => {
        console.log(successful);
      },
      onError: errors => {
        console.log(errors)
      },
     
      onFinish: (visit) => {
        setLoading(false);
      },
    });
  };

values here is a simple json :

{
email: “[email protected]”,
email:MyPasswordForTest00,
remember:true,
}

now on the backend :

 public function Login(Request $request, $as)
    {
        $credentials = $request->validate([
            email' => ['required', 'email'],
            password' => ['required'],
        ]);

        if (Auth::attempt($credentials, $request->remember)) {
            $request->session()->regenerate();

            return redirect()->intended('dashboard');
        }


        return back()->withErrors('message', 'password incorrect');
    }

when I execute a dd() , I see that I'm in the right method the problem is that

->withErrors()

I have already tried to :

• change the inertia middleware, it has no effect, in the client:

  const { errors } = usePage().props;

  useEffect(() => {
    if (errors) {
      Object.keys(errors).forEach((key) => {
        message.error(errors[key]);
      });
    }
    console.log(errors)
  }, [errors]); // here is still empty :(

the error pocket is still empty and I'm not redirected :_(
