Error in firewall check on second run

[vitkhab]

On second run of ansible-playbook playbook.yml I'm getting error

TASK [Ensure firewall rule for kubernetes-the-hard-way internal is present] *****************
fatal: [localhost]: FAILED! => {"changed": false, "failed": true, "msg": "Unexpected response: ('<' not supported between instances of 'NoneType' and 'NoneType').

Looks like it's a bug of gce_net module but workaround would be appreciated.
