Anyproxy is not working on localhost

I run `anyproxy --port 9999 --intercept --rule ./rules.js`, and have the SwitchyOmega running.
It intercept the API response in Staging site. But is not working in localhost.
Do I need to configure something to make it run on localhost?

My rules.js is something like this.
```
module.exports = {
*beforeSendResponse(requestDetail, responseDetail) {
require.cache = {};

if (
/favorites/.test(requestDetail.url) &&
requestDetail.requestOptions.method == "GET"
) {
const response = responseDetail.response;
const mock = require("./data/favorites");
response.body = JSON.stringify(mock);
return { response };
}
}
};
```

#### Which platform are you running AnyProxy

Mac

#### The version of the AnyProxy

4.1.0

#### Your expected behavior of AnyProxy

Anyproxy can intercept API response on localhost.

#### The actual behavior of AnyProxy

Anyproxy doesn't catch anything from localhost request.

#### The log of the error

Start with the `anyproxy --port 9999 --intercept --rule ./rules.js` command and the `beforeSendResponse` hook in `rules.js`; compare how staging and localhost requests reach the proxy. Done means the localhost API response is intercepted and the configured mock response is returned.
