ansible/jinja extract multiple attributes from complex json return, rejecting specific matches

I'm trying to extract multiple attributes from a complex payload returned from an API call while rejecting members that have a certain value in the 'name' field. Consider the following payload:

    "failed": false,

    ]
}

}

From this return, I need to store the "name" and "wwn" fields for each volume. Additionally, I need to reject any volume that contains "_os" in the "name" field.

I can get the information using a json_query, but haven't figured out how to reject the volumes with "_os" in their names using this approach.

- name: Set volume name and WWN
  set_fact:
    volume_pairs: "{{ npod_volumes | json_query(volume_query) }}"
  vars: 
    volume_query: "volumes[].{name: name, wwn: wwn}"
  tags: volumes

This gives the following output which includes the unwanted "VMware_Lenovo_server-09.tme.nebulon.com_os" volume.

ok: [127.0.0.1] => {
"volume_pairs": [
    {
        "name": "VMware_Lenovo_VV7",
        "wwn": "6f497c2006187474000ab00000007000"
    },
    {
        "name": "VMware_Lenovo_VV4",
        "wwn": "6f497c2006187474000ab00000004000"
    },
    {
        "name": "VMware_Lenovo_server-09.tme.nebulon.com_os",
        "wwn": "6f497c2006187474000ab00000000000"
    }
]

}

Thanks in advance for your time and consideration!

So I landed on this solution. Using 'rejectattr' I omit all volumes that contain "_os" in the name. Probably could be done in a more elegant way that excludes my needing to use a json query, but it gets the job done.

  - name: Filter out OS volumes
    set_fact:
      shared_volumes: "{{ npod_volumes.volumes | 
                        rejectattr('name', 'contains', '_os') | 
                        sort(attribute='name') | list }}"
    register: result
    tags: volumes  

  # This builds a list of volumes names and their WWNs
  - name: Set volume name and WWN
    set_fact:
      volume_pairs: "{{ shared_volumes | json_query(volume_query) }}"
    vars: 
      volume_query: "[].{name: name, wwn: wwn}"
    tags: volumes
