Can't Deploy to vCenter

Deploying new host on vCenter gives error:
Failed to create a compute vCenter (VMware) instance undefined method `attributes’ for #String:0x007fb787396c78

Expected outcome:
Host is created and provisioned

Foreman and Proxy versions:
Latest, 17.0 and Puppet 5.x

Foreman and Proxy plugin versions:
Completely new install from 4/29/18

Other relevant data:
[e.g. logs from Foreman and/or the Proxy, modified templates, commands issued, etc]

This is Bug #23378: Unable to create a VM on 1.17.0 on vCenter 6.5. - Foreman which is planned for 1.17.1.

Ah, okay, thanks!
