Rule UnauthorizedError behaves differently between my two apps. I want to use your error pages

I have 2 apps

1 is the sample .NET 2.1 from yourselves.
The other is our Discourse tenant.

I have a rule that validates the email domain.

When I try to access the Discourse app with a user that causes the rule to throw a UnauthorizedError I am correctly sent to one of your hosted error pages that includes the UnauthorizedError message under technical details. This is great!

When I perform the same login via the .NET Core web app I am instead redirect to the /callback endpoint of the .net core app … I would rather be sent to your error page so I don’t have to create and handle the error in the app.

How do I make the .NET core web app behave like the discourse app?

Discourse is using SSO configuration.

Discourse is constructing this:

https://{tenant}.eu.auth0.com/authorize?client_id={clientid}&response_type=code

The .NET App is some what different:
https://{tenant}.eu.auth0.com/authorize?client_id={clientid}&redirect_uri=https://{myappurl}/callback&response_type=code&scope=openid&response_mode=form_post&nonce={nonce}&state={state}&x-client-SKU=ID_NETSTANDARD1_4&x-client-ver=5.2.0.0

My money is that because the redirect_uri is specified it expects my app to handle the error.

Is there a way for me to change the .NET Core app code so it doesn’t specify the this?

Anyone able to support?
