OS / ENVIRONMENT

Red Hat Enterprise Linux release 9.1 (Plow)

Desired Behavior

Meaningful error message, for example: "Unable to log in to Private Automation Hub", or perhaps "Failed to authenticate", or "Incorrect username or password"

Actual Behavior

Getting the following error: "An unhandled exception occurred while running the lookup plugin 'infra.ah_configuration.ah_api'. Error was a <class 'TypeError'>, original message: expected string or bytes-like object. expected string or bytes-like object"

STEPS TO REPRODUCE

Make query via API like so:

- name: Get list of published collections
  ansible.builtin.set_fact:
    published_collections: "{{ query('infra.ah_configuration.ah_api',
                                     'collections',
                                      host=hub_config_host,
                                      username=hub_config_user,
                                      password=hub_config_pass,
                                      verify_ssl=false) }}"

specifying incorrect credentials in hub_config_user/hub_config_pass.

Get an error message that doesn't make any sense:

{
  "msg": "An unhandled exception occurred while running the lookup plugin 'infra.ah_configuration.ah_api'. Error was a <class 'TypeError'>, original message: expected string or bytes-like object. expected string or bytes-like object",
  "_ansible_no_log": false
