How to fetch attribute in freeradius plicy.d/filter

Question

I have an issue with getting empty Called-Station-Id in policy.d/filter of Freeradius. there are different VLANs the user can connect from I want to assign VLAN by filtering the WIFI name in the request packet EX: Called-Station-Id = "1A-EC-DA-8A-FD-73:WIFIRadius".

filter

filter_ssid {
        if ("%{Called-Station-Id}" =~ /WIFIRadius/) {
                 update reply {
                        Tunnel-Type = VLAN,
                        Tunnel-Medium-Type = IEEE-802
                        Tunnel-Private-Group-Id = 10
                        Reply-Message = "Authenticated as %{User-Name} CSID: %{Called-Station-Id}"
                 }
                 ok
         }
        elsif ("%{Called-Station-Id}" =~ /WIFIRadius2/) {
                  update reply {
                        Tunnel-Type = VLAN
                        Tunnel-Medium-Type = IEEE-802
                        Tunnel-Private-Group-Id = 15
                        Reply-Message = "Authenticated as %{User-Name} CSID: %{Called-Station-Id}"
                 }
                 ok
         }
}

Thu Mar 30 10:42:15 2023 : Debug: (7)       } # policy filter_ssid = notfound

the filter_ssid is liste in sites-enabled/default and inner-tunnel after filter_username

User-Name is being passed in filter with value but Called-Station-Id is empty. I am using: freeradius 3.0 Authentication: EAP-GTC

any help how I can get this Called-Station-Id in filter with value in it.
