Description of problem:

Ansible inventory script/Ansible Tower is getting an HTTP 500 error when attempting to synchronize inventory with Red Hat Satellite 6.6.  Without filters we are able to sync the inventory without any issue.

Satellite role/Filter:-

Version-Release number of selected component (if applicable):
Satellite 6.6

How reproducible:


Steps to Reproduce:
1. Create the role/filters as mentioned above.
2. Create a ansible user and associate the role.
3. Provision a new host then check whether you are able to list using ansible inventory script or tower.

Curl command is also failing with 500 error:-

# curl -k -v -u ansible:redhat  -H "Content-Type: application/json" https://satellite/api/v2/hosts/12/facts?per_page=250&page=1

Output:-

{
  "error": {"message":"Can't join 'Host::Base' to association named 'subscription_facet'; perhaps you misspelled it?"}
}


Actual results:

Getting below error:- 

error": {"message":"Can't join 'Host::Base' to association named 'subscription_facet'; perhaps you misspelled it?"}

Expected results:

We should be able to sync the inventory without any issue.
