Isilon / Powerscale Ansible Module Errors: Invalid value for snapshot_sync_pattern

Hi,

I am having problems with the 9.x Ansible Powerscale/Isilon Modules.  Specifically the dellemc_powerscale_synciqpolicy module.

When doing a simple get:

- name: Get SyncIQ policy details
  dellemc_powerscale_synciqpolicy:
    onefs_host: "{{ dr_onefs_host }}"
    port_no: "{{ dr_port_no }}"
    verify_ssl: "{{ verify_ssl }}"
    api_user: "{{ dr_api_user }}"
    api_password: "{{ dr_api_password }}"
    policy_name: "{{ policy_name }}"
    state: "present"

I get an error:

"msg": "Get details of SyncIQ policy Ansible_policy failed with error : Invalid value for `snapshot_sync_pattern`, length must be greater than or equal to `1`"

Can someone tell me what I'm doing wrong?

Thanks.

Glenn
