Cannot pass all-in-one-mode assertion

[jessequinn]

What happened?

TASK [cloudalchemy.cortex : Services should be empty when all-in-one-mode is enabled] **************************************************************************************************************************************************
fatal: [cortex]: FAILED! => {
    "assertion": "cortex_all_in_one == (cortex_services|length == 0)",
    "changed": false,
    "evaluated_to": false,
    "msg": "Exactly one of cortex_all_in_one or cortex_services should be set."
}

Did you expect to see some different?

expected to pass assertion.

How to reproduce it (as minimally and precisely as possible):

- hosts: all
   roles:
    - cloudalchemy.cortex

Environment

Hi, I am also facing the same issue.. so found quick work around for this assertion task as below.
preflight.yml:
tasks:

       - name: Services should be empty when all-in-one-mode is enabled
         assert:
            that: cortex_all_in_one == (cortex_services|length == 0)| bool
            msg: "Exactly one of cortex_all_in_one or cortex_services should be set."
         when: cortex_services is defined or (cortex_all_in_one | default(true) == false)
