Return value of carsAction() must be of the type array, object returned

Question

My code inside carsAction() function:

return $this->renderView(
     'WebsiteBundle:SearchCars:cars.html.twig',
    [ 'cars' => $cars ]
);

And I get the error:

Return value of carsAction() must be of the type array, string returned

I tried to change renderView to render

return $this->render(
    'WebsiteBundle:SearchCars:cars.html.twig',
            [ 'cars' => $cars ]        
);

but get this error:

Return value of carsAction() must be of the type array, object returned

Answer 1

Solution:

Instead of the array I change the method definition like this

 * @return Response
 */


public function carsAction(Request $request): Response
