Read data from firebase and display in chat using Node Js
I am new to the Firebase realtime database and Google Dialogflow. I have gone through the documents and working on through. I am reading the data from database and I want to display it in my chat. I am able to see the data in the logs but unable to display in the chat conversation. If I check the logs I am able to see the success or failed result but unable to view in the chat conversation.
This is the code below:
var childData = "";
var message = '';
var query = '';
var key = '';
function wheretogo(agent) {
//taking country name as input from user
var country = request.body.queryResult.parameters.country;
//reference country from the database
query = admin.database().ref("country").orderByKey();
query.once("value")
.then(function(snapshot) {
snapshot.forEach(function(childSnapshot) {
key = childSnapshot.key;
childData = childSnapshot.val();
//matching the input from user and the country name(key) from database
if (country === key) {
console.log("sucess");
message = 'Thats nice ! You are travelling to ' + key;
agent.add(message);
}
else
{
console.log("failed");
}
});
});
}
I expect the output 'Thats nice ! You are travelling to ' with country name in my chat conversation.

The problem is that the Dialogflow library expects you to return a Promise if you're doing any asynchronous calls. Since you're doing an async call (the query.once() call), you must return a Promise. Otherwise the handler dispatcher won't wait for the reply to come from the database before it tries to send a reply to the user.
You don't show all of your code, but in your case it looks fairly straightforward. Since query.once() returns a Promise, you can return this Promise. Something like this change
return query.once("value")
might be all that is necessary.
