Repro

The Issue is described in this discussion #1222

Basic summary is that the the environment variable WEBSITE_AUTH_LOGOUT_PATH has been deprecated with App Service Authentication v2 (Easy Auth) so I get the below exception when logging out.

Expected behavior
The user should be logged out of the Easy Auth session.

Actual behavior
The following exception is thrown

Value cannot be null or empty: (Parameter: 'localUrl')

Possible solution

@navyasric what would be your recommendation?

• EasyAuth took a breaking change by not adding the logout path environment variable in v2 where it would be added in v1.
• if auth is enabled on the app (the enabled env var is set to true), then we can assume no WEBSITE_AUTH_LOGOUT_PATH environment variable to mean that the logout path is at WEBSITE_AUTH_API_PREFIX/logout, and if now api prefix is specified, then the logout path is at the default "/.auth/logout"

Fixed in 1.13 release.

What a great turnaround, 13 days from reporting to being added to the code base. Thanks so much for this. I have just tested today and can confirm that this has resolved my issue.
