Ansible and Vsphere

All , i have searched many sites but i am able to get this playbook to work. I am trying to build a vm via ansible and i get the following error message below. I have also posted my playbook. Any help would be greatly appreciated.

Thanks in advance,

Seems like there is an indentation problem. Try:

vm_disk:
disk1:
size_gb: 1
type: thin
datastore: Comoy-SAN
vm_nic:
nic1:
type: vmxnet3
network: Example_Application_10.10.10.0_24_VLAN10
network_type: standard
