bigip_pool_member error "\"pool\" unexpected argument"

Usually, the examples straight out of the docs usually work fine. I can create the pool but I can't add members. I am using partitions. Anyone know where to go from here? Here is my playbook excerpt.

    - name: Create a pool
      bigip_pool:
        state: present
        partition: BILLING
        provider: "{{ provider }}"
        lb_method: ratio-member
        name: my-pool
        slow_ramp_time: 120
      delegate_to: localhost

    - name: Add pool member With Options
      bigip_pool_member:
        pool: my-pool
        partition: BILLING
        host: "10.2.2.5"
        port: 80
        description: web server
        connection_limit: 100
        rate_limit: 50
        ratio: 2
        provider: "{{ provider }}"
      delegate_to: localhost

I have the following output.

TASK [Create a pool] *******************************************************************************************************************************
ok: [localhost -> localhost]

TASK [Add pool member With Options] ****************************************************************************************************************
fatal: [localhost -> localhost]: FAILED! => {"changed": false, "msg": "\"pool\" unexpected argument"}

My traceback looks like this:
