Hi, I am trying to integrate Auth0 with a sample Nodejs application but getting the following error. Anyone plz help.

Express is running on port 3000:
TypeError: Cannot read properties of undefined (reading ‘isAuthenticated’)

I had the same issue.

Just make sure that the Auth configuration is before the app.use, not after.

Example:
Before:

app.use('/', indexRouter);
app.use('/users', usersRouter);

// auth router attaches /login, /logout, and /callback routes to the baseURL
app.use(auth(config));

After(works):

// auth router attaches /login, /logout, and /callback routes to the baseURL
app.use(auth(config));
app.use('/', indexRouter);
app.use('/users', usersRouter);
