I have created the react client tutorial.  
[https://developer.okta.com/quickstart/#/react/dotnet/aspnet4](https://developer.okta.com/quickstart/#/react/dotnet/aspnet4)

When I click login, I get the Okta login screen. Upon submitting the login seems to succeed, but, I get a page that says ‘AuthApiError’.

My network tab in chrome looks like this:

My Home.js is an exact copy of the file from the tutorial.
