Problem getting complete .pem from ansible letsencrypt / acme_certificate module - ssl

Question

I was using Ansible 2.4 and included the letsencrypt module in one of my roles hoping to get a complete `.pem' format file at the end (key, chain, cert). There was no problem generating the key or using the csr to request the new cert, and no problem with the challenge, but when everything was done, I was only getting the certificate back, no chain.
When I tried to use them, Apache would fail to start saying that the key and the cert did not match. I assumed that this was because I didn't include the chain which was missing.
According to the docs here: https://docs.ansible.com/ansible/latest/modules/acme_certificate_module.html the chain|chain_dest and fullchain|fullchain_dest parameters weren't added until Ansible 2.5. So I upgraded to Ansible 2.7 (via git), and I'm still running into the exact same error...
FAILED! => {
"changed": false,
"msg": "
Unsupported parameters for (letsencrypt) module: chain_dest, fullchain_dest
Supported parameters include: account_email, account_key, acme_directory, agreement,
challenge, csr, data, dest, remaining_days"
}
I've tried the aliases and current names for both but nothing is working. Here is my current challenge-response call:
- name: Let the challenge be validated and retrieve the cert and intermediate certificate
letsencrypt:
account_key: /etc/ssl/lets_encrypt.key
account_email: ###########.###
csr: /etc/ssl/{{ myhost.public_hostname }}.csr
dest: /etc/ssl/{{ myhost.public_hostname }}.crt
chain_dest: /etc/ssl/{{ myhost.public_hostname }}.int
fullchain_dest: /etc/ssl/{{ myhost.public_hostname }}.pem
challenge: dns-01
acme_directory: https://acme-v01.api.letsencrypt.org/directory
remaining_days: 60
data: "{{ le_com_challenge }}"
tags: sslcert
The documentation says that this is valid, but the error response does not include chain|chain_dest or fullchain|fullchain_dest as valid parameters.
I would, from the docs, expect that this response should result in the new certificate being created (.crt), the chain being created (.int), and the fullchain to be created (.pem).
Any help would be appreciated.

Should have waited 5 minutes... seems that the newer parameters are only available under the newer module name acme_certificate, even though it says letsencrypt was a valid alias. As soon as I updated this it worked.
