      .Capsule sync fails due to a null value in UUID of a host

      When you attempt to sync Capsule in certain setups with an improperly registered host, the sync fails due to a null value in the `uuid` column of the `hosts` database table.
      To work around this problem, delete such host from Satellite and register it anew.
      As a result, the host UUID is correctly set, which resolves the sync failure.

      Additional Information:

      If executing this command on satellite i.e. 

      cat << EOF | foreman-rake console
conf.echo = false
SmartProxy.all.each do |sp|
  pp sp.name
  pp sp.content_facets.where(uuid: nil)
end
EOF

       

      Then in the output, under satellite and every capsule, some records should be displayed. And they would indicate the ID of hosts. If found any like that, Then re-register those hosts or else remove them from Satellite WebUI and that should allow syncing the capsule . 

      If the output indicates no such broken hosts, then the issue must have got resolved itself, and a subsequent capsule sync should not run into the same issue again.
