无法访问 Dialogflow webhook 参数

Question

I have a webhook in DF however my web service cannot seem to get the JSON messages sent from DF. How to access the object that would have DF's responses using node.js. Currently, my function is accepting a variable called req but req.body or req.queryResult doesn't seem to access DF parameters. Any help would be appreciated. My code is below which doesn't print any parameters from DF:

app.post("/", (req, res) => {
 console.log(req.body.queryResult.parameters);

You don't indicate what middleware, if any, you have setup for this route.

You should be using the express.json() middleware, which will set req.body to a JavaScript object that should, at a minimum, contain the queryResult attribute.
