Unable to create a hostset in primera y using hpe3par_hostset module

[baba-dudekula]

I'm getting the below error when executing an ansible playbook to create a hostset in Primera.
`- name: Primera_hostset | Create or Delete HostSet
when: 'hostset_action is defined and hostset_action in ["absent", "present"]'
block:
- name: Primera_hostset | Create or Delete HostSet
hpe3par_hostset:
storage_system_ip: "{{ storage_system_ip }}"
storage_system_username: "{{ storage_system_username }}"
storage_system_password: "{{ storage_system_password }}"
state: "{{ hostset_action }}"
hostset_name: "{{ storage_hostset_name }}"

setmembers: "{{ hostset_members | default(omit) }}"

  register: rg_hostset_action`

Error:
fatal: [localhost]: FAILED! => {
"changed": false,
"invocation": {
"module_args": {
"domain": null,
"hostset_name": "ms-host-catalogue",
"setmembers": null,

"storage_system_password": "VALUE_SPECIFIED_IN_NO_LOG_PARAMETER",
"storage_system_username": "VALUE_SPECIFIED_IN_NO_LOG_PARAMETER"
}
},
"msg": "Hostset creation failed | Internal Server Error (HTTP 500) 1 - internal server error"
}

How ever i'm able to access the primera over api and login from successfully.
