HTTP 405 Method Not Allowed Lumen/Laravel - laravel

Question

im trying to build an auth api for my react using lumen/laravel , each time i want to test it out with postman i get the following error HTTP 405 Method Not Allowed .
my routes :
$router->group(['prefix' => 'patient'], function () use ($router) {
$router->post('register',[PatientAuthController::class,'register'] );
$router->post('login', [PatientAuthController::class,'login'] );
});
CorsMiddlware :
class CorsMiddleWare
{
/**
* Handle an incoming request.
*
* #param \Illuminate\Http\Request $request
* #param \Closure $next
* #return mixed
*/
public function handle($request, Closure $next)
{
//Intercepts OPTIONS requests
if ($request->isMethod('OPTIONS')) {
$response = response('', 200);
} else {
// Pass the request to the next middleware
$response = $next($request);
}
// Adds headers to the response
$response->header('Access-Control-Allow-Methods', 'HEAD, GET, POST, PUT, PATCH, DELETE');
$response->header('Access-Control-Allow-Headers', $request->header('Access-Control-Request-Headers'));
$response->header('Access-Control-Allow-Origin', '*');
$response->header('Access-Control-Expose-Headers', 'Location');
// Sends it
return $response;
}
PatientAuthController :
protected $patient;
protected $utilityService;
public function __construct()
{
$this->middleware("auth:patient",['except'=>['login','register']]);
$this->patient = new Patient;
$this->utilityService = new UtilityService;
}
public function register(PatientRegisterRequest $request)
{
$password_hash = $this->utilityService->hash_password($request->password);
$this->patient->createPatient($request,$password_hash);
$success_message = "registration completed successfully";
return $this->utilityService->is200Response($success_message);
}
/**
* Get a JWT via given credentials.
*
* #param Request $request
* #return Response
*/
public function login(LoginRequest $request)
{
$credentials = $request->only(['email', 'password']);
if (! $token = Auth::guard('patient')->attempt($credentials)) {
$responseMessage = "invalid username or password";
return $this->utilityService->is422Response($responseMessage);
}
return $this->respondWithToken($token);
}
