Social Sign-In, logout error

AndyH5 days ago

APEX 24.2

Using Social Sign-In with OpenId.

Sign-In works without issues, but on logging out, the user sees the message:

Error processing request.
Contact your application administrator.
Return to application.

The URL showing in their browser is of the form:

https://myapp.mydom.com/myords/apex_authentication.logout?p_app_id=123@p_session_id=12345678

which looks good to me.

Turned on extra debugging, which shows:

Debug Row 1

Patch Version=5
SID=241
USER=APEX_PUBLIC_USER
ECID=hki4buuE0QYQM5V-UhgmYw
PROXY_USER=ORDS_PUBLIC_USER
INSTANCE=1

The callstack for the above shows:

%ERROR.debug_error:1868

- Statement:

The home URL is: f?p=&APP_ID.:1:&SESSION.

The logout URL is: f?p=&APP_ID.:LOGIN_DESKTOP:&SESSION.

Page 101 has the alias of login_desktop.

Any ideas?
