      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.
