18,527 Pointsauthentication error
Hello, I'm attempting to use the sign-in function on this app exercise. When I sign into the app it, displays the <h1>{authUser.name} is Authenticated</h1> and the <p>Your username is {authUser.username}</p>
as is expected. Although, when I refresh the browser I get the error Cannot read properties of null (reading 'name')
On line 6 on Authenticated.js. I've tried changing the useState initial value into an empty object; (unlike the video's code). When I do this the app no longer crashes, but stops showing the {authUser.name} and {authUser.username}.
I've console logged the info on the Authenticated page and it is just receiving that empty object. How can I get this function to work correctly after a refresh?

Treehouse StaffHey Killeon Patterson 👋
That behavior is to be expected at this point of the course. When refreshing the page the authUser state declared in the userContext refreshes back to the initial value of null. In the final stage of the course Laura will explain how to setup cookies to persist the data of the currently signed in user.
