when defined not working with hash

[jepper]

I need to do something like this in a role, and I use an endpoint for some of the items in the hash I feed it

  shell: dosomething.sh {{ item.endpoint }}

  when: "{{ item.endpoint }} is defined"

  with_items: {{ myhash }}

myhash:

  - { version: '{{ cqrs_version }}' }

  - { version: '{{ staging_version }}', endpoint: 'http://localhost:8080/staging' }

It breaks as follows:

figured it out. Simply

when: "item.endpoint is defined"
