remote PAC with custom witelist

[qqrm]

I'm using a proxy with my own whitelist, through which traffic is routed. For this, I modified the local PAC. My rule list looks like this:

var __USERRULES__ = [];
var __RULES__ = [
  "@@||/.*/", // block all
  // *domains allowed list*
];

Everything works quite well with the local PAC. However, I wanted to upload my local PAC to a gist and use it via a URL. But when I use my rules through a URL, the proxy stops working.

In the logs, I see:

It seems that something else needs to be specified, but my search did not yield the required result, so I am asking for help. Or am I fundamentally doing something wrong?
