updating out of date api controller documentation

[MZandtheRaspberryPi]

I am new to oatpp and trying to use it for a project. I got some errors following some of the code snippets in the APIController documentation. This was mentioned on this issue by someone else: oatpp/oatpp#556.

Namely this gives me an error:

ENDPOINT("GET", "/users/{userId}", getUserById,
         PATH(Int64, userId)) 
{
  OATPP_LOGD("Test", "userId=%d", userId->getValue());
  return createResponse(Status::CODE_200, "OK");
}

error: request for member ‘getValue’ in ‘*(& userId)->oatpp::data::mapping::type::Primitive<long int, oatpp::data::mapping::type::__class::Int64>::<anonymous>.oatpp::data::mapping::type::ObjectWrapper<long int, oatpp::data::mapping::type::__class::Int64>::operator->()’, which is of non-class type ‘long int’
[build]    52 |   OATPP_LOGD("Test", "userId=%d", userId->getValue());

And this compiles:

ENDPOINT("GET", "/users/{userId}", getUserById,
         PATH(Int64, userId)) 
{
  OATPP_LOGD("Test", "userId=%d", *userId);
  return createResponse(Status::CODE_200, "OK");
}
