问题 I'm playing around with building a simple Facebook Messenger chatbot and I'm having trouble sending messages in sequence. In the example above, it should have printed "Hello!", "1", "2", "3" in order. I'm currently following the Facebook docs found here to implement this simple text message function. I've included my Express Node.JS server code below: Defining the sendTextMessage() function: var request = require("request"); function sendTextMessage(user, text) { messageData = { text: text };
