Implement ResolverCollection in cakephp 4.2

I was using the mapResolver in the site, but now changed to ResolverCollection and is giving me the exception “Return value of App\Application::getAuthorizationService() must be an instance of Authorization\AuthorizationServiceInterface, instance of Authorization\Policy\ResolverCollection returned”.
This is the code for getAuthorizationService:

	public function getAuthorizationService(ServerRequestInterface $request): AuthorizationServiceInterface {
		$ormResolver = new OrmResolver();
		$mapResolver = new MapResolver();
		$mapResolver->map(ServerRequest::class, RequestPolicy::class);
		return new ResolverCollection([$mapResolver, $ormResolver]);
	}

How do I have to write the code for the getAuthorizationService method so that it doesn’t give me that exception?

The example code in the docs shows:

public function getAuthorizationService(ServerRequestInterface $request): AuthorizationServiceInterface
{
    $resolver = new OrmResolver();

    return new AuthorizationService($resolver);
}

So your implementation should also be returning a new AuthorizationService object which might take your MapResolver as an argument.

Here is some example code from my own app:

    public function getAuthorizationService(ServerRequestInterface $request): AuthorizationServiceInterface
    {
        $resolver = new OrmResolver();
        $mapResolver = new MapResolver();
        $mapResolver->map(ServerRequest::class, RequestPolicy::class);
        $mapResolver->map(IdPackage::class, IdAccessPolicy::class);
        $mapResolver->map(StackSet::class, StackSetPolicy::class);
        $mapResolver->map(OrderWrapper::class, OrderLifecylePolicy::class);

        $resolverCollection = new ResolverCollection([$resolver, $mapResolver]);

        return new AuthorizationService($resolverCollection);
    }
