Parsing resource content $res

Hi there, I am using windmill v1.513.1 and I define an Input which has type array and item type "Items are resources". Now, the ressources are passed to the next step as something like "$res:/path/to/resource". This $res is breaking everything. Is it intended to appear and how do I parse the resource in a subsequent script using the go-library's GetResource(string) ? Thanks for hints
