How could I detect an Intent with a context ? (node.js SDK for Dialogflow API V2) - node.js

Question

How could I detect an Intent with a context ?
I defined an Intent "Book" with an input Context "Activity", then trained my bot with "Book this activity in my schedule".
I don't want to use dialog flow to manage context flow because it may evolve from other inputs in my app. So I want pass it as a parameter for each intent detection.
I use node.js SDK for Dialogflow API V2.
I precise it works fine with REST API v1 ... I think i'm stuck with API v2 Contexts :)
I'm looking to do exactly the same as the following code with API v2
//code below is working fine
import apiai from 'apiai';// Dialogflow SDK v1
import uuidv4 from 'uuid/v4';
const sessionId = uuidv4();
const api = apiai('myToken');
const lang = 'en-US';
const request = api.textRequest('Book this activity in my schedule', {
sessionId,
lang,
contexts : [{ name : 'activity' }],
});
request.on('response', function(response) {
console.log(response);
});
request.on('error', function(error) {
console.log(error);
});
request.end();
I didn't found documentation or exemple to do that except API documentation so I probably did something wrong
Whenever I pass a context as a queryParams or create a Context it don't work.
It also seems that context creation from API don't work at all.
import dialogflow from 'dialogflow';//Dialogflow SDK v2
import uuidv4 from 'uuid/v4';
const projectId = 'myID';
const sessionId = uuidv4();
const languageCode = 'en-US';
const sessionClient = new dialogflow.SessionsClient();
const contextClient = new dialogflow.ContextsClient();
const sessionPath = sessionClient.sessionPath(projectId, sessionId);
...
First try returned my Default Fallback Intent :
const request = {
session : sessionPath,
queryParams : {
context : {
parent : sessionPath,
name : contextClient.contextPath(
projectId,
sessionId,
'activity'
),
},
},
queryInput : {
text : {
text : 'Book this activity in my schedule',
languageCode : languageCode,
},
},
};
sessionClient.detectIntent(request)
.then(responses => {
const result = responses[0].queryResult;
if (result.intent) {
console.log(result.intent.displayName);
} else {
console.log(' No intent matched.');
}
});
Second try returned my Default Fallback Intent :
contextClient
.createContext({
parent : sessionPath,
context : {
name : contextClient.contextPath(
projectId,
sessionId,
'activity'
),
},
})
.then(() => contextClient.listContexts({ parent : sessionPath }))
.then(contexts => {
console.log(contexts);//returned an empty list
return sessionClient.detectIntent(request);
}).then(responses => {
const result = responses[0].queryResult;
if (result.intent) {
console.log(result.intent.displayName);
} else {
console.log(' No intent matched.');
}
});
Anybody see what's wrong with it ?
Help needed :)

Had same issue.
Found that I need to send "lifespanCount" greated than 0.
{
"session": "projects\/verifier-26084\/agent\/sessions\/1gg5b76c37f7111b",
"queryParams":
{
"contexts": [
{
"name": "projects\/verifier-26084\/agent\/sessions\/1gg5b76c37f7111b\/contexts\/ask-children",
"lifespanCount": 1
}]
},
"queryInput":
{
"text":
{
"text": "\u0442\u0440\u0438",
"languageCode": "ru-RU"
}
}
}
