Unable to manage mappings via proxy

[nicolai86]

POST/ PUT requests fail when using aws-es-kibana:

_http_outgoing.js:346
    throw new Error('Can\'t set headers after they are sent.');
    ^

Error: Can't set headers after they are sent.

    at _combinedTickCallback (internal/process/next_tick.js:74:11)
    at process._tickDomainCallback (internal/process/next_tick.js:122:9)

triggered by PUTting a mapping with curl

@nicolai86 Is this still happening with the latest version, can you please advise?

Yep (v1.0.5).

@santthosh I abandoned this package for a golang based alternative which never showed similar issues.
