Wit.ai Clear or Reset context - wit.ai

Question

How can I reset or clear the context at the end of my story or when the user wants to restart the process ? I already have a reset function of my own ... Not very effective ! Can you please explain me what I have to do ? Thank you very much
reset({sessionId,context}) {
return new Promise(function(resolve, reject) {
context = null;
return resolve(context);
});
}
And for the session, I do that :
var findOrCreateSession = (fbid) => {
let sessionId;
Object.keys(sessions).forEach(k => {
if (sessions[k].fbid === fbid) {
sessionId = k;
}
});
if (!sessionId) {
console.log("je cree une session car yen a pas");
sessionId = new Date().toISOString();
sessions[sessionId] = {
fbid: fbid,
context: {}
};
}
return sessionId;
};
How can I kill the session at the end of the story and/or kill context and reset the process please !

You could potentially delete the old session and create a new one before the webhook hits the Wit.ai controller.
See the code below for an example:
Webhook POST handler
// Conversation History
let sessionId = WitRequest.getSession(senderId);
if (message.text.toLowerCase() == "break") {
// New Conversation History
// Delete the old session
WitRequest.deleteSession(sessionId);
// Get new Session Id
sessionId = WitRequest.getSession(senderId);
}
let sessionData = WitRequest.getSessionData(sessionId);
wit.runActions(
sessionId,
message.text,
sessionData
)
.then((context) => {
sessionData = context;
})
.catch((error) => {
console.log("Error: " + error);
});
WitRequest Class
static getSession(senderId) {
let sessionId = null;
for (let currentSessionId in sessions) {
if (sessions.hasOwnProperty(currentSessionId)) {
if (sessions[currentSessionId].senderId == senderId) {
sessionId = currentSessionId
}
}
}
if (!sessionId) {
sessionId = new Date().toISOString();
sessions[sessionId] = {
senderId: senderId,
context: {}
}
}
return sessionId;
}
static getSessionData(sessionId) {
return sessions[sessionId].context;
}
static deleteSession(sessionId) {
delete sessions[sessionId];
}
static clearSession(session) {
session.context = {};
}
