[BUG] - Error creating server: {"message":"please provide only one os_id, app_id, or snapshot_id","status":400}

[michaelspringer]

Describe the bug

When attempting to build an image using 'snapshot_id' with 'os_id', or building with only 'snapshot_id', the API returns:

'please provide only one os_id, app_id, or snapshot_id","status":400}'

I am unable to find a combination of configuration options to build from a snapshot. (Also same with problem with iso_id)

To Reproduce

{
 "variables": {
        "vultr_api_key": "XXXXX",
        "vultr_ssh_pwd": "XXXXX"
    },
    "builders": [{
        "type": "vultr",
        "api_key": "{{ user `vultr_api_key` }}",
        "snapshot_description": "Packer-test-with updates",
        "region_id": "dfw",
        "plan_id": "vc2-1c-1gb",
        "os_id": 164,
        "snapshot_id": "673f3943-c844-4e28-99f4-eef7d97a42b1",
        "state_timeout": "15m",
        "ssh_username": "root",
        "ssh_password": "{{ user `vultr_ssh_pwd` }}"
    }]
}

Error

$ packer build test.json
