What is the improvement or update you wish to see?

Report here claims to have fixed the error on the docs but it still didn’t include const SIGNIN_ERROR_URL = "/error"; as reported.

Is there any context that might help us understand?

I have to include the const myself as well as add the signOut:”/signout” which is also not included in the custom signout page docs reference.

Does the docs page already exist? Please link to it.
