Error when adding the 'beforeRecord' event

Hey, I’ve been testing pollyjs in my Ember app, and it worked fine. Later I’ve added the beforeRecord event like this:

    server
      .any()
      .on('beforeRecord', (req, recording) => {
        console.log(recording);
      });

and got this error (it goes away when I remove it):

pollyjs-core.js:2 Uncaught (in promise) TypeError: Cannot assign to read only property 'params' of object '#<l>'
    at pollyjs-core.js:2
    at tryCatch (polyfill.js:6900)

(btw it’d be nice if source maps would work when in dev mode, so that it would be easier to debug issues like this)

@jasonmit thanks! works great now 👍 also I agree, the response event makes more sense for this use case 😃

@piotrpalek that error you were seeing about the read-only object should now be fixed on master and will be part of the 0.1.0 release that is going out in a few minutes.

That said, I still believe for your use case you want to use the response event (formerly known as beforeResponse).
