Ansible synchronize (rsync) fails - ssh

Question

ansible.posix.synchronize, a wrapper for rsync, is failing with message
"msg": "Warning: Permanently added <host> (ECDSA) to the list of known hosts.\r\n=========================================================================\nUse of this computer system is for authorized and management approved use\nonly. All usage is subject to monitoring. Unauthorized use is strictly\nprohibited and subject to prosecution and/or corrective action up to and\nincluding termination of employment.\n=========================================================================\nrsync error: received SIGINT, SIGTERM, or SIGHUP (code 20) at rsync.c(644) [sender=3.1.3]\n"
My playbook
---
- name: Test rsync
hosts: all
become: yes
become_user: postgres
tasks:
- name: Populate scripts/common using copy
copy:
src: common/
dest: /home/postgres/scripts/common
- name: Populate scripts/common using rsync
ansible.posix.synchronize:
src: common/
dest: /home/postgres/scripts/common
Populate scripts/common using copy executes with no problem.

Notes:
User pg_deployment has passwordless sudo to postgres. This ansible playbook is being run inside a docker container.
After messing with it a bit more, I found that I can directly run the rsync command (not using ansible)
SSHPASS=<my_ssh_pass> sshpass -e /usr/bin/rsync --delay-updates -F --compress --archive --rsh='/usr/bin/ssh -S none -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null' --rsync-path='sudo -u postgres rsync' --out-format='<<CHANGED>>%i %n%L' common pg_deployment#<host>:/home/postgres/
The only difference I can see is I used sshpass -e while ansible defaulted to sshpass -d#. Could the credentials ansible was trying to pass in be incorrect? If they are incorrect for ansible.posix.synchronize then why aren't they incorrect for other ansible tasks?
EDIT
Confirmed that if I run
sshpass -d10 /usr/bin/rsync --delay-updates -F --compress --archive --rsh='/usr/bin/ssh -S none -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null' --rsync-path='sudo -u postgres rsync' --out-format='<<CHANGED>>%i %n%L' common pg_deployment#<host>:/home/postgres
(I chose random number for the file descriptor d10) I get the same error as above
"msg": "Warning: Permanently added <host> (ECDSA) to the list of known hosts.\r\n=========================================================================\nUse of this computer system is for authorized and management approved use\nonly.

Suggesting that the problem is whatever ansible is using as the file descriptor? It isn't a huge problem since I can just pass in the sshpass as an env variable in my docker container since it's ephemeral, but I still would like to know what is going on with ansible here.
