Ansible and route53 unsupported parameter for module: connection - dns

Question

I'm trying to run an Ansible playbook with Amazon's Route53 service but I get the error in the title.
$ ansible-playbook play-dns.yml
PLAY [localhost] **************************************************************
GATHERING FACTS ***************************************************************
ok: [localhost]
TASK: [configure dns] *********************************************************
failed: [localhost] => {"failed": true}
msg: unsupported parameter for module: connection
FATAL: all hosts have already failed -- aborting
PLAY RECAP ********************************************************************
to retry, use: --limit #/home/myuser/play-dns.retry
localhost : ok=1 changed=0 unreachable=0 failed=1
This is my play:
$ cat play-dns.yml
---
- hosts: localhost
tasks:
- name: configure dns
route53:
command: create
aws_access_key: 'XXXXXXXXXXXXXXXXXXXX'
aws_secret_key: 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
zone: myzone.info
record: test.myzone.info
type: A
ttl: 7200
value: 1.1.1.1
wait: yes
connection: local
And this is my Ansible hosts file:
$ cat /etc/ansible/hosts|grep localhost
[localhost]
localhost ansible_connection=local
If I remove ansible_connection=local from the hosts file
$ cat /etc/ansible/hosts|grep localhost
[localhost]
localhost
then I get this error:
$ ansible-playbook play-dns.yml
PLAY [localhost] **************************************************************
GATHERING FACTS ***************************************************************
fatal: [localhost] => SSH Error: ssh: connect to host localhost port 22: Connection refused
while connecting to 127.0.0.1:22
It is sometimes useful to re-run the command using -vvvv, which prints SSH debug output to help diagnose the issue.
TASK: [configure dns] *********************************************************

FATAL: all hosts have already failed -- aborting
PLAY RECAP ********************************************************************

localhost : ok=0 changed=0 unreachable=2 failed=0
What am I doing wrong?

Your issue is simply indentation. Currently Ansible is parsing your playbook and seeing the connection line as a parameter to the route53 module which is then complaining that connection is not a valid parameter for the module.
Instead you simply need to unindent the line to the same level as the hosts so that Ansible parses it as a parameter to the playbook overall rather than the module:
---
- hosts: localhost
connection: local
tasks:
- name: configure dns
route53:
command: create
aws_access_key: 'XXXXXXXXXXXXXXXXXXXX'
aws_secret_key: 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
zone: myzone.info
record: test.myzone.info
type: A
ttl: 7200
value: 1.1.1.1
wait: yes
