I'm running this in a centos8 container and my facter.conf file is:

facts : {
blocklist: [ "EC2" ],
cache: true
ttls: [

{ "kernel" : 8 hour }

,

{ "memory" : 8 hour }

,

{ "networking" : 8 hour }

,

{ "operating system" : 8 hour }

,

{ "processor" : 8 hour }

,
]
}

Note this worked fine with facter 3.14.
