Documentation Bug introduced by
It seems like array() of type array is incompatible with the declared type resource of property $resultSet.

Our type inference engine has found an assignment to a property that is incompatible with the declared type of that property.

Either this assignment is in error or the assigned type should be added to the documentation/type hint for that property..
