Does postJson('/login') instead of post('/login') work?

Testing Inertia with Validation
I wonder if anyone can help me out here.
I have a login form built using Inertia and Vue (I know I could use Breeze) and I'm trying to test the validation (using Pest). The test keeps insisting that Invalid JSON was returned from the route. and I'm not sure why. It certainly returns JSON in the browser with a Content-Type: application/json header, after redirecting. The status assertion is passing so I know the test is following redirects as expected.
public function create(): RedirectResponse
{
$validator = validator([
'email' => 'required',
'password' => 'required',
]);
$validator->validate();
return redirect('/login');
}
it('requires an email and password')
->followingRedirects()
->post('/login')
->assertStatus(200)
->assertJsonFragment(['email']);

@lolsokje I'm afraid not, the result is the same.

Post the method it redirects to

@Sinnbeck I'm just about to look at it, but as far s :I can tell, the Inertia middleware handles a 422 by adding the validation errors and redirecting itself. At least, that's what happens in the browser.

@normykinz you are indeed correct. Ignore what I said.

My best suggestion is to rewrite to a functional test instead of higher order, which should let you dd the response
Or add dd() to the chain and see if you get anything useful

If anybody's having the similar problems, here's how managed to iron things out ...
public function create(LoginRequest $request): RedirectResponse
{
return redirect('/login');
}
class LoginRequest extends FormRequest
{
protected $redirect = "/login";
public function rules()
{
return [
'email' => 'required',
'password' => 'required',
];
}
}
it('requires an email and password')
->followingRedirects()
->post('/login')
->assertInertia(fn (Assert $page) => $page
->component('auth/Login')
->has('errors.email')
->has('errors.password'));
