everyone I try to follow the tutorial to build my first bot.
But when I use Bot Framework Emulator to connect it, It don't show Hello World on Emulator.
And when I send some thing word(like 'test' or 'P') to server, It crash can show me
Error: connect ECONNREFUSED 127.0.0.1:5631
at Object.exports._errnoException (util.js:1022:11)
at exports._exceptionWithHostPort (util.js:1045:20)
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1090:14)
how can i fix it?
