I am using Node.js with the Microsoft Bot Framework. When the user opens a connection to my bot, for example, just using the simulator, I would like the bot to initiate the conversation with a welcome message and some basic instructions.

The documentation says to use the bot.beginDialog, however, I cannot get their examples to work; they just throw a 500 error.

Does anyone have a simple, working example of using the bot.beginDialog method to initiate a conversation?
