title: Skype bot built with skype-sdk in Node.js is not running correctly?
body: <p>I am trying to build skype bot.</p>
  
  <p>I followed documentation given by <code>skype-sdk</code> but failed to create it using that. Can not get reply from bot.</p>
  
  <pre><code>const fs = require('fs');
  const restify = require('restify');
  const skype = require('skype-sdk');
  
  const botService = new skype.BotService({
      messaging: {
          botId: 'xxxxxxxx-xxx-xxx-xxx-xxxxxxxxxxxx',
          serverUrl : "https://example.net",
          requestTimeout : 15000,
          appId: 'xxxxxxxx-xxx-xxx-xxx-xxxxxxxxxxxx',
          appSecret: 'xxxxxxxxxxxxxxxxxxxxxxxx'
      }
  });
  
  botService.on('contactAdded', (bot, data) =&gt; {
      console.log("bot replay");
      bot.reply('Hello ${data.fromDisplayName}!', true);
  });
  
  botService.on('personalMessage', (bot, data) =&gt; {
      console.log("person replay");
      bot.reply('Hey ${data.from}. Thank you for your message: "${data.content}".', true);
  });
  
  const server = restify.createServer();
  
  server.use(skype.ensureHttps(true));
  server.use(skype.verifySkypeCert({}));
  
  server.post('/skbot', skype.messagingHandler(botService));
  const port = process.env.PORT || 8080;
  server.listen(port);
  console.log('Listening for incoming requests on port ' + port);
  </code></pre>
  
  <p>Thanks</p>
