vmware_guest module error: Failed to find a matching datastore

[DSS]

Hello,

I am testing the vmware_guest module to snapshot a VM but it returns an error message with any invocation of module. According to the documentation (https://docs.ansible.com/ansible/vmware_guest_module.html), i'm using ansible development version (ansible 2.3.0 (devel 86db15b105)) and the required parameters of module for vcenter connection.

The error message is  "msg": "Failed to find a matching datastore"

Removing the snapshot part and testing with ansible 2.2, the error is diferent: KeyError: 'template'

The task involved:

- vmware_guest:
    validate_certs: False
    hostname: "{{ vcenter.ip }}"
    username: "{{ vcenter.username }}"
    password: "{{ vcenter.password }}"
    datacenter: "{{ vcenter.datacenter }}"
    name: "{{ vm2snap | upper }}"
    state: poweredoff
    #snapshot_op:
    #  op_type: create
    #  name: snap_osp
    #  description: {{ vm2snap }} snapshot.
