Error at task "Add new hosts to the dynamic inventory"

[hubitor]

I'm getting the following error when I run the playbook:

TASK [siw36.ansible_hcloud_vm : Add new hosts to the dynamic inventory] ***************************************
fatal: [localhost]: FAILED! => {"msg": "Invalid data passed to 'loop', it requires a list, got this instead: [{'server': AnsibleUndefined, 'ipv4': AnsibleUndefined, 'ipv6': AnsibleUndefined}]. Hint: If you passed a list/dict of just one element, try adding wantlist=True to your lookup invocation or use q/query instead of lookup."}

[siw36]

Seems like the return variables of the hcloud_server module were empty. Did the deployment of the VM succeed?

[hubitor]

Did the deployment of the VM succeed?

Nope.

EDIT

In the previous step I get this:

TASK [siw36.ansible_hcloud_vm : Create server inventory] *********************************************
ok: [localhost] => (item={'changed': False, 'hcloud_server': None, 'invocation': {'module_args': {'api_token': 'VALUE_SPECIFIED_IN_NO_LOG_PARAMETER', 'name': 'test0.nodes.replicas.io', 'server_type': 'cx11', 'image': 'centos-7', 'location': 'hel1', 'backups': False, 'ssh_keys': ['root'], 'state': 'absent', 'labels': {'project': 'project-test-07', 'stage': 'prod', 'location': 'helsinki'}, 'upgrade_disk': False, 'force_upgrade': False, 'endpoint': 'https://api.hetzner.cloud/v1', 'id': None, 'datacenter': None, 'user_data': None, 'volumes': None, 'rescue_mode': None}}, 'failed': False, 'item': {'name': 'test0.nodes.replicas.io', 'state': 'absent', 'size': 'cx11', 'location': 'hel1', 'image': 'centos-7', 'backup': False, 'sshKeys': ['siw'], 'labels': {'project': 'project-test-07', 'stage': 'prod', 'location': 'helsinki'}, 'volumes': [{'name': 'test0.nodes.replicas.io-data0', 'state': 'absent', 'size': 10, 'automount': True, 'format': 'xfs'}]}, 'ansible_loop_var': 'item'})

So, if the error stems from 'hcloud_server': None how can fix it?

[siw36]

It seems like you have not replaced all example variables like 'sshKeys': ['siw']
