PHP 8.1: Deprecated function: strrpos(): Passing null to parameter #1 ($haystack) of type string is deprecated in restws_page_callback()

Upgraded to Restws 2.10 the patch applied in this is already there for $id_arg and for $resource_arg it was missing hence adding the additional updates

$id_arg or $resource_arg could be null, and in PHP 8 that is no longer allowed to be passed to most string functions.
