Mashup + ESP8266

Hi Team!
  I try to send any sensors measurements from my board to my Mashup.
  The code is worked in this url: https://blog.avotrix.com/esp8266-with-thingworx/ but the code has crashed like the printscreen. My library was recently downloaded, in another sketchs its works as well! How I can fix it?
  Follow to My Mashup and prototype board.

Thanks to all.
Telles.
