I'm new to Azure and Azure Bot Framework. I was starting my basic bot (generated with Azure itself and with some adjustments to simplify the bot to have a better understanding afterwards), but after npm start
I got this error:
TypeError: userState.createProperty is not a function
I've searched on Azure documentation, here and wherever I could, but I didn't find a solution yet. Here is the code that caused the error:
const USER_PROFILE_PROPERTY = 'USER_PROFILE_PROPERTY';
/* some code */
this.luisRecognizer = luisRecognizer;
this.userState = userState;
this.userProfileAccessor = userState.createProperty(USER_PROFILE_PROPERTY);
And here is the full error trace:
C:UsersUsernameDesktopotdirectorydialogsmainDialog.js:36
this.userProfileAccessor = userState.createProperty(USER_PROFILE_PROPERTY);
^

EDIT:
To give more context, I was using as reference this dialog to implement my main dialog, and here there's not userState.createProperty<PropertyAccessor>
, that's why I didn't know it would be necessary, so I'll give it a try.
About where to find userState
, here is the code (it's in a different file, the error is in my mainDialog.js
, userState
comes from index.js
):
/** all require are omitted **/
const memoryStorage = new MemoryStorage();
const conversationState = new ConversationState(memoryStorage);
const userState = new UserState(memoryStorage);
const { LuisAppId, LuisAPIKey, LuisAPIHostName } = process.env;
const luisConfig = { applicationId: LuisAppId, endpointKey: LuisAPIKey, endpoint: `https://${ LuisAPIHostName }` };
const luisRecognizer = new StreamAdvLuis(luisConfig);
const userState = new UserState(memoryStorage);
//My main dialog
const dialog = new MainDialog(luisRecognizer, userState);
//My bot
const bot = new DialogBot(conversationState, userState, dialog);
const server = restify.createServer();
server.listen(process.env.port || process.env.PORT || 3978, function() {
console.log(`
${ server.name } listening to ${ server.url }`);
console.log('
Get Bot Framework Emulator: https://aka.ms/botframework-emulator');
console.log('
To talk to your bot, open the emulator select "Open Bot"');
});
// Listen for incoming activities and route them to your bot main dialog.
server.post('/api/messages', (req, res) => {
// Route received a request to adapter for processing
adapter.processActivity(req, res, async (turnContext) => {
// route to bot activity handler.
await bot.run(turnContext);
});
});
// Listen for Upgrade requests for Streaming.
server.on('upgrade', (req, socket, head) => {
// Create an adapter scoped to this WebSocket connection to allow storing session data.
const streamingAdapter = new BotFrameworkAdapter({
appId: process.env.MicrosoftAppId,
appPassword: process.env.MicrosoftAppPassword
});
// Set onTurnError for the BotFrameworkAdapter created for each connection.
streamingAdapter.onTurnError = onTurnErrorHandler;
streamingAdapter.useWebSocket(req, socket, head, async (context) => {
// After connecting via WebSocket, run this logic for every request sent over
// the WebSocket connection.
await bot.run(context);
});
});
