OAuth authentication with Azure Active Directory app - node.js

Question

I am trying to run the OAuth example in the botbuilder nodejs documentation at https://github.com/Microsoft/BotBuilder/blob/master/Node/examples/basics-oauth/app.js
I have set up the Azure Active Directory v1 application on Azure with graph api access and have added the OAuth connection to my bot. The connectionName to be used in the code below is ready with me.
But when I run the code which is taken as is from the documentation (the github link provided above), I am getting:
TypeError: connector.getUserToken is not a function
I have run this both on emulator and on webchat channel and getting the same error.
// Create your bot with a function to receive messages from the user
var bot = new builder.UniversalBot(connector, function (session) {
if (session.message.text == 'signout') {
// It is important to have a SignOut intent
connector.signOutUser(session.message.address, connectionName, (err, result) => {
if (!err) {
session.send('You are signed out.');
} else {
session.send('There was a problem signing you out.');
}
});
} else {
// First check whether the Azure Bot Service already has a token for this user
connector.getUserToken(session.message.address, connectionName, undefined, (err, result) => {
if (result) {
// If there is already a token, the bot can use it directly
session.send('You are already signed in with token: ' + result.token);
} else {
// If there not is already a token, the bot can send an OAuthCard to have the user log in
if (!session.userData.activeSignIn) {
session.send("Hello! Let's get you signed in!");
builder.OAuthCard.create(connector, session, connectionName, "Please sign in", "Sign in", (createSignInErr, signInMessage) =>
{
if (signInMessage) {
session.send(signInMessage);
session.userData.activeSignIn = true;
} else {
session.send("Something went wrong trying to sign you in.");
}
});
} else {
// Some clients require a 6 digit code validation so we can check that here
session.send("Let's see if that code works...");
connector.getUserToken(session.message.address, connectionName, session.message.text, (err2, tokenResponse) => {
if (tokenResponse) {
session.send('It worked! You are now signed in with token: ' + tokenResponse.token);
session.userData.activeSignIn = false;
} else {
session.send("Hmm, that code wasn't right");
}
});
}
}
});
}
})

According to your error message, could you please double check your local botbuiler version, as the getUserToken function is added in 3.15.0, and you can find the definition at https://github.com/Microsoft/BotBuilder/blob/botbuilder%403.15.0/Node/core/src/bots/ChatConnector.ts, which doesn't show up before this version.
