Description

Updates the src/Pods/REST/V1/Endpoints/Base.php file to explicitly mark the parameters as nullable instead of implicitly, which is deprecated.

Note that some additional testing would be appreciated with older PHP versions. I went with ? instead of |null for better backwards compatibility. This method should be supported in PHP 7.1 and above:
