Add YAML fields only if variable is set

Hi,

I have the following code:

action: |
  {% if target is defined and target == "xxxx" %}
    notify.mobile_app_xxxx_handy
  {% elif target is defined and target == "yyyy" %}
    mobile_app_iphone_von_yyyy
  {% else %}
    notify.all_phones
  {% endif %}
data:
  message: "{{ body }}"
  title: "{{ header }}"
  data:
    subtitle: "{{ message }}"
    url: "{{ url }}"
    actions: |
      {% if action1_title is defined and action1_action is defined %}
      - action: "{{ action1_action }}"
        title: "{{ action1_title }}"
      {% endif %}
      {% if action2_title is defined and action2_action is defined %}
      - action: "{{ action2_action }}"
        title: "{{ action2_title }}"
      {% endif %}

The part with the actions is not working, because the result is:

actions: |-
        - action: "TEST_123"
          title: "Test"

So the characters “|” and “-” were added after “actions:”. Due to those signs the action button is not visible at the iOS notification.

So how can I add action buttons (title and id) only if I set them in the variables (action1_title, action1_action and action2_title, action2_action) ? I don’t want to have multiple condition in my automations / scripts, because then I have duplicated code.
