body property is always empty .on('resourceReceived')

[hoodoos]

I try to get a body of XHR call using .on('resourceReceived', function(response){ ... }), but response.body is always empty or null. Is there anyway to overcome it?

Same issue, anyone could help?

It's because the communication between Horseman and PhantomJS is asynchronous. When your .on callback get called in NodeJs the PhantomJS callback has already run and the body is gone.

You can use .at to register a callback that runs in PhantomJS instead of NodeJS and it will have access to the response.

It seems like that the issue is associated with PhantomJS itself, the response body from PhantomJS is empty. I've also tried .at and the result is same:
