Discord notification with multiple text selector as image

Hi,

I’m trying to make a script/blueprint to send a discord message with multiple images. It works well with a single one, multiple when I do not use inputs, but when it comes to using inputs and multiple, then I receive a discord message without any images inside.

Here is the code:

alias: Discord notification
fields:
  title:
    description: Notification title
    example: Title
    required: true
    selector:
      text: null
  message:
    description: Notification message
    example: Message
    required: true
    selector:
      text: null
  color:
    description: Notification color
    example: green
    required: true
    selector:
      select:
        options:
          - green
          - orange
          - red
  channel:
    description: Discord channel
    example: general
    required: true
    selector:
      select:
        options:
          - general
          - security
  image:
    description: Image filename path
    example: /tmp/entity_id.name
    required: false
    selector:
      text:
        multiline: true
        prefix: /tmp/
        multiple: true
sequence:
  - service: notify.home_assistant
    data:
      message: ""
      target: |
        {% if channel == "security" %}
          xxx
        {% else %}
          yyy
        {% endif %}
      data:
        embed:
          description: |
            {{ message }} {{ now().strftime('\n\n%d-%m-%Y at %H:%M:%S') }}
          url: https://xxx/
          author:
            name: "{{ title }}"
          color: |
            {% if color == "red" %}
              15548997
            {% elif color == "orange" %}
              15105570
            {% else %}
              5763719
            {% endif %}
        images: |
          {% for item in image %}
          - {{ item }}
          {% endfor %}
icon: mdi:message-badge-outline
mode: queued
max: 100

When I look into traces, I can see:

      images: |-
        - xxx.jpg
        - yyy.jpg
        - zzz.jpg

If I try to manually add those images without |-, it works well:

      images:
        - xxx.jpg
        - yyy.jpg
        - zzz.jpg

It looks like a jinja templating issue, any idea how to fix this?

Thanks a lot in advance
