generaterequest catch() in parent scope has no error info

See this SO question for more info:

Particularly the comment to the accepted answer:

This approach works only if the catch handler is in the same scope as the generateRequest() call. What can be done if the request is fired in a method that returns the promise, with a catch handler in a parent scope?

I'll try and make a quick demo...
