Error when the bot subscribes to "message_echoes"

[johntiror]

driver version: 1.0.2

If in the facebook bot developer console you subscribe the bot also to the "message_echoes", after the first message the bot will sto working since the driver does not support the echoes.

The error returned is:
Error sending payload: (#100) Tried accessing nonexisting field (first_name) on node type (Page) (500 Internal Server Error)

in order to reproduce simply subscribe the bot to "message_echoes" and than send a couple of messages, the bot will never answer the second message. Note: subscribing to a new field has a lag (few mins), keep in mind in case the bot will continue working.
