How do I trigger LUIS in all dialogs retaining the previous context? - node.js

Question

I am developing a bot with Microsoft Bot Framework, LUIS and node.js .This bot is based on Microsoft Teams and I am using TeamsBotSsoPrompt and Microsoft-Graph for authentication of the user.
The authentication step in the AUTH_DIALOG is as follows:
async showUserInfo(stepContext) {
const tokenResponse = stepContext.result;
if (tokenResponse) {
try {
// Call Microsoft Graph on behalf of user
const oboCredential = new OnBehalfOfUserCredential(tokenResponse.ssoToken);
//console.log("oboCredential> " + JSON.stringify(oboCredential));
const graphClient = createMicrosoftGraphClient(oboCredential, this.requiredScopes);
const me = await graphClient.api("/me").get();
const lanID = await graphClient.api("/me/onPremisesSamAccountName").get();
if (me) {
var authHeaders = {
"user": me.userPrincipalName,
"token": tokenResponse.token,
header1: null,
header2: null,
header3: null,
}
userName = me.givenName;
authHeaders['name'] = userName;
await stepContext.context.sendActivity({ type: ActivityTypes.Typing });
await stepContext.context.sendActivity(`Hello! <b>` + userName + `</b>`);
await stepContext.context.sendActivity({ type: ActivityTypes.Typing });
await stepContext.context.sendActivity("Let's get started.How can I help you?");
return await stepContext.beginDialog(FLOW_DIALOG, authHeaders);
} else {
await stepContext.context.sendActivity({ type: ActivityTypes.Typing });
await stepContext.context.sendActivity("Getting profile from Microsoft Graph failed! ");
return await stepContext.endDialog();
}
}
catch (error) {
// error logged here
}
}
else {
await stepContext.context.sendActivity({ type: ActivityTypes.Typing });
await stepContext.context.sendActivity("Login was not successful please try again.");
return await stepContext.endDialog();
}
}
The FLOW_DIALOG is where I have LUIS enabled.From the FLOW_DIALOG, I redirect the bot to other dialogs based on the Intent.But when I am in that other dialog and if I enter something in the bot, the current dialog ends and returns the flow to the FLOW_DIALOG. I want all the dialogs to trigger LUIS and move the flow to the correct Intent Dialog.
The FLOW_DIALOG is as follows:
async introStep(stepContext) {
const ActionCard = utility.createSuggestedActions(suggestionList, suggestionTitle);
await stepContext.context.sendActivity({ type: ActivityTypes.Typing });
await stepContext.context.sendActivity({ attachments: [ActionCard] });
return { status: DialogTurnStatus.waiting };
}
async actStep(stepContext) {
const luisRecognizer = new LuisRecogniser(luisConfig, stepContext.dialogs.telemetryClient);
let authHeaders = stepContext.options;
if (!luisRecognizer.isConfigured) {
return await stepContext.context.sendActivity("Something went wrong. Please Contact Your Administrator");
}
const luisResult = await luisRecognizer.executeLuisQuery(stepContext.result ? stepContext.result : stepContext.context);
topIntent = LuisRecognizer.topIntent(luisResult);
switch (topIntent) {
case "Intent1": {
authHeaders['header1'] = luisResult.entities;
return await stepContext.beginDialog(DIALOG_A, authHeaders);
}
case "Intent2": {
authHeaders['header2'] = luisResult.entities;
return await stepContext.beginDialog(DIALOG_B, authHeaders);
}
// ... and other intents in similar way
}
}
Now, I did try adding the LUIS to the onMessage call but I couldn't access the context.options to set or reset the authHeaders that I have. I know the context there is DialogContext and the one we get access to is TurnContext.
So is it possible to alter the headers values and pass it along the dialog calls and also trigger LUIS for every message the user enters from whichever Dialog the user currently has access to.

Having LUIS integrated within Waterfall dialogs seems not supported. It worked fine in case of TextPrompt but I find no way to do that when we have 'ChoicePrompt' or 'ConfirmPrompt'.
We can have LUIS integrated to decide which dialog to start and for the same sample is also available - Core bot.
You can also refer this link to have idea on how to use dialogs in bot - https://learn.microsoft.com/en-us/azure/bot-service/bot-builder-concept-waterfall-dialogs?view=azure-bot-service-4.0#using-dialogs
