title: Google dialogflow small talk issue
body: <p>i am developing chat bot application with google dialog flow. i am using node js client <a href="https://github.com/dialogflow/dialogflow-nodejs-client-v2" rel="nofollow noreferrer">https://github.com/dialogflow/dialogflow-nodejs-client-v2</a> to access the data of my chat bot. i have enabled small talk from the dialog flow console and it works fine when i use it from the dialog flow web demo or the console it self</p>

  <p>for the same chat application i have implemented a api by using dialogflow node js client.</p>
  
  <pre><code> if (req.body.text) {
          query = req.body.text;
      }
      // Get the city and date from the request
      var request = {
          session: sessionPath,
          queryInput: {
              text: {
                  text: query,
                  languageCode: languageCode,
              },
          },
      };
      // Send request and log result
      sessionClient
          .detectIntent(request)
          .then(responses =&gt; {
              console.log('Detected intent');
              const result = responses[0].queryResult;
              console.log(`  Query: ${result.queryText}`);
              console.log(`  Response: ${result.fulfillmentText}`);
              if (result.intent) {
                  res.json({ "text": result.fulfillmentText });
              } else {
                  res.json({ 'fulfillmentText': "No intent matched" });
                  console.log(`  No intent matched.`);
              }
          })
          .catch(err =&gt; {
              console.error('ERROR:', err);
          }); 
  </code></pre>
