How to get user's id from auth0 in React

Question

I recently implemented user authentication in my react web app using Auth0. And I need to retrieve some information from user object. I did this so far:

cost { user, isAuthenticated } = useAuth0();
<p>{user.name}</p>

But I also want to get user's id, so I can reference them later in my backend. So I did this:

const { user, isAuthenticated } = useAuth0();
<p>{user.user_id}</p>

And when I go to the website I get undefined instead of the user's id.

Is it happening because I use dev-keys for my social connections, or maybe it has to be done differently?

Not sure if you are still searching for this problem, however I had a similar problem and found this as a solution:

const { user, isAuthenticated } = useAuth0();
<p>{user.sub}</p>
