Description of problem:
When creating a VMWare host through Hammer, I get an undefined method error. It is entirely possible that I'm doing something wrong but the error doesn't help me much. No traceback, foreman-tail attached.

Version-Release number of selected component (if applicable):
Reproduced on Sat 6.6 snap 20.

How reproducible:
Deterministic

Steps to Reproduce:
1.Run hammer host create command. I ran:

1. hammer host create --compute-resource testvmware --lifecycle-environment Library --content-view "Default Organization View" --content-source "$(hostname)" --architecture x86_64 --location "Default Location" --organization "Default Organization" --name "lhellebr-hammer-thick-thick" --domain-id 1 --subnet-id 1 --root-password secretpassword --image vmware-image1 --operatingsystem "RedHat 7.7" --provision-method image --interface "compute_type=VirtualE1000,compute_network=dvportgroup-647,domain-id=1,subnet-id=1"

Actual results:
Could not create the host:
Failed to create a compute testvmware (VMware) instance lhellebr-hammer-thick-thick.lab.eng.bos.redhat.com: undefined method `[]' for nil:NilClass

Expected results:
Host created successfully or some useful error.
