If Anonymous authentication is not enabled for your application, you will encounter the error: authentication via 'anon-user' is unsupported.

To correct this issue, enable Anonymous authentication using the App Services UI (or App Services Admin API).

1. In the left-hand navigation of the App Services UI, click Users -> Providers.

2. Click EDIT to update the Allow users to log in anonymously provider.

3. Toggle Provider Enabled to ON and click Save.

4. Click Review & Deploy in the top blue banner to deploy the change to your production application. For more information on reviewing and deploying changes, see Deploy from the App Services UI and Why are the user modifications made to the App Services UI not reflected in the App Services Application?.

5. After the changes are deployed, the Allow users to log in anonymously provider displays as enabled.
