Using lookup plugin within include_vars to build file name

[Sam Sen]

Running Ansible 2.1.1

I want to dynamically build the variable name for a file I wish to load using "include_vars." it doesn't work using the lookup plugin but the lookup plugin itself does work when I use the "debug" method.

- name: load var file
  include_vars: "{{ lookup('ini','environment section=environment_info file=/etc/abc123.conf') }}.yml"

Error:

TASK [sam : load var file] *****************************************************
task path: /home/ssen/ansible_ops/roles/sam/tasks/main.yml:5
An exception occurred during task execution. The full traceback is:

Can you workaround it by setting a variable to the result of your
lookup and then use this variable for the file name?

Yes that's what I ended up doing. I'm not sure why I'm not able to use the lookup plugin within the line.
