.catch transformRequest / transformResponse errors

I might be missing something here (saw #61 and #110 related), but…

Looks like there’s no way to .catch in the Promise control flow any error occurring during the transform phase, e.g. here: https://github.com/mzabriskie/axios/blob/master/lib/adapters/xhr.js#L12-L17 you’d need to try {} catch {} transformData() and reject accordingly the Promise

Is this deliberate?

I think It’s ok to have your own error handlers in transformResponse like you say here: https://github.com/mzabriskie/axios/issues/110#issuecomment-142682301 , but what if the user wants to handle errors down the Promise chain? (In my experience this is the expected way of handling errors when dealing with a Promise-based api)

Can we reopen this issue? I just stumbled upon this as well. Promise-based api should handle all errors as reject or at least provide a mechanism for the user to call reject. With the current api I have to do this

axios({
  transformResponse: [data => {
    try {
      //... data
    } catch(e) {
    }
    return null;
  }]
}).then(resp => {
  if (resp == null) {
    throw new Error('NULL!');
  }
  return resp;
})

Which is not ideal.

This was solved after a refactor a few versions ago.
