Service doesn't support chkconfig using ansible, works fine through service service_name start/stop

Question

I have an init.d unit file which works fine through command line:

service ibmihs.service [start/stop]

However when I run through ansible it run successfully but the service won't start. I see this error in the log:

  "stderr": "service ibmihs.service does not support chkconfig\n",

I am using Ansible Automation Platform Controller 4.3.0 and Red Hat Enterprise Linux Server release 6.10 (Santiago)

playbook:

- name: Include variables file
  ansible.builtin.include_vars:
    file: ../environments/Development/group_vars/role1/main.yml

- name: Start IBM HTTP Server administration server [adminctl]
  become: yes
  ansible.builtin.sysvinit:
    name: "{{ ibm_adminctl_service_file }}"
    state: started
    enabled: yes
    
  when:
    hostvars[inventory_hostname].ansible_distribution_major_version == "6"
  
- name: Start IBM HTTP Server administration server [adminctl]
  become: yes
  ansible.builtin.service:
    name: "{{ ibm_ihs_service_file }}"
    state: started
    enabled: yes
    
  when:
    hostvars[inventory_hostname].ansible_distribution_major_version >= "7"
