    Hi

    Have you tried storing the xxf header as an APM variable right at the start when then policy first fires....?

    when HTTP_REQUEST {
if {[HTTP::header exists X-Forwarded-For]}{
set xff [HTTP::header values X-Forwarded-For]
}
}
 
when ACCESS_SESSION_STARTED {
if {[info exists xff]}{
ACCESS::session data set session.custom.xff $xff
}
}

    If the value is saved as an APM variable then you should be able to manipulate it (or take action if it is empty) further on in the APM policy

It seems that ACCESS_POLICY_AGENT_EVENT is not linked to connection but to access policy evaluation in an asynchronous context... it doesn't have access to connection variables...
