ansible Failed to create temporary directory despite ansible_system_tmpdirs: "/var/tmp"

Question

Below is my ansible playbook and the specific task that fails:

- name: My Playbook
  hosts: AppServer
  gather_facts: true
  become: yes
  vars:

    ansible_remote_tmp: "~/.ansible/tmp"
    ansible_system_tmpdirs: "/var/tmp"  
    tomcat_home: "{{ hostvars[inventory_hostname]['tomcat_home_input'] }}"

  tasks:
    ...
    ...
      - name: Ensure the target directory is deleted (if it exists)
        ansible.builtin.file:
          path: "{{ tomcat_home_item | trim }}/aredeploy"
          state: absent
        register: directory_deleted
        ignore_errors: yes
        become: true
        become_user: "{{ become_user_global }}"

Output:

ok: [remhost77] => {
    "msg": "/root/mydir/package-571-DEV.zip"
}

remhost77               : ok=18   changed=4    unreachable=1    failed=0    skipped=2    rescued=0    ignored=0   

If i change from /var/tmp/ to just tmp i get the below error:

{
  "msg": "Failed to set permissions on the temporary files Ansible needs to create when becoming an unprivileged user (rc: 2, err: chmod: ERROR: Different file system ACL types cannot be merged: /tmp/ansible-tmp-1708941960.8785305-121-146387316011020/\nchmod: ERROR: Different file system ACL types cannot be merged: /tmp/ansible-tmp-1708941960.8785305-121-146387316011020/AnsiballZ_file.py\n}). For information on working around this, see https://docs.ansible.com/ansible-core/2.12/user_guide/become.html#risks-of-becoming-an-unprivileged-user",
  "_ansible_no_log": false
}

Note:

• There are several tasks by olamuser (ansibleuser) on the target that works fine before it errors on the above task. The conclusion i can make is that there is no issue with the account we are using to execute the tasks as it partially performs many tasks.

• I do not have option to change any ansible config file as this ansible trigger is using OLAM docker process managed by a different team. I can just make changes to the playbook code.

Below are the details of the /var/tmp directory.

wladmin@remhost77$ ls -ld /var/tmp
drwxr-xr-x   3 root     root          15 Feb 26 03:37 /var/tmp

and

wladmin@remhost77$ ls -ltr /var/tmp
total 83

I reffered to the below links before posting:

Ansible error "failed to create temporary directory"

remote tmp directory not set for ansible script execution

Can you please suggest?
