Error when running bigip_command Playbook against LTM : Syntax Error: unexpected argument /bin/sh\n

I am running a Playbook to test bigip_command using ansible [core 2.15.3] against LTM running 15.1.6.1. When I run the playbook I get the following message:

UNREACHABLE! => {
“changed”: false,
“msg”: “Failed to create temporary directory. In some cases, you may have been able to authenticate and did not have permissions on the target directory. Consider changing the remote tmp path in ansible.cfg to a path rooted in "/tmp", for more error information use -vvv. Failed command was: ( umask 77 && mkdir -p "echo $HOME/tmp"&& mkdir "echo $HOME/tmp/ansible-tmp-1709037153.0021555-3167181-73985055078518" && echo ansible-tmp-1709037153.0021555-3167181-73985055078518="echo $HOME/tmp/ansible-tmp-1709037153.0021555-3167181-73985055078518" ), exited with result 1”,
“unreachable”: true
}

When I run the Playbook with -vvv flags I see the following line just before the error message pasted above: Failed to connect to the host via ssh: Syntax Error: unexpected argument “/bin/sh”

Similarly, if I test the ssh I also see this same unexpected argument message:

ansible all -m shell -a id -vvv

Syntax Error: unexpected argument “/bin/sh”\n’

I have tried editing various things in hosts file and ansible.cfg but nothing I have tried seems to have made a difference. Is anyone familiar with this and what is needed to resolve this. Any help is greatly appreciated!
