Are you sure print_r(getenv(), true) of type string|true can be used in concatenation?

                    get_class($lazyValue->getWrappedValueHolderValue())

It seems like $lazyValue->getWrappedValueHolderValue() can also be of type null; however, parameter $object of get_class() does only seem to accept object, maybe add an additional type check?
