I am running

`

- name: Install logstash {{ logstash\_apt\_version }}  
apt:  
pkg: “logstash={{ logstash\_apt\_version }}”  
state: present  
force: “{{ logstash\_apt\_force | default(false) }}”  
environment: “{{ logstash\_environment | default(omit) }}”  
register: apt\_logstash  
notify: restart logstash  
`

Where in this case `environment is not defined`, and I get this warning. Why would this be?

`
