Why validation works wrong?

This is validation rule:

$validator = Validator::make($request->all(), [
            'email' => 'required|array',
            'email.*' => 'required|email'
        ]);

        if ($validator->fails()) {
            throw new ValidationException($validator);
        }

This data that with header: application/json, text/plain, */* Content-Type: application/json I send using client:

[{"email":"oli35@mail.ru"},{"email":"zakaji-buket@mail.ru"}]
