dhcp.relay is not working in version 4.0.0 master

[Katuri, Vikram]

Hi Team,

I am trying to setup a freeradius DHCP Load balancer with config given in https://github.com/FreeRADIUS/freeradius-server/blob/master/raddb/sites-available/dhcp.relay , and I am facing trouble doing it.
I am using 4.0.0 version and the git checkout tag is 5309825993e5c61a4b2551d9799ba41ff141478c

Please find the 'radius -X' o/p below
