Bug 26312: (follow-up) Fix passing of exception messages

'error' has special meaning in exceptions so naming the fields:
type, details

Rather than only dealing with a single exception type, we generically
get the ES exception info and pass it up.

I could not recreate timeout still, however, I simply restarted the
ES docker during commit stage to cause NoNodes exceptions
