Custom icon in switch template won't show

Configuration
8

I found this: https://community.home-assistant.io/t/animated-svg-icons/52615/3

And I use: https://shapeshifter.design/ to make animation svg files.

Then I put all svg files to folder /local/icons/kodi-playing/.

my template:

entity_picture_template: >-
  {% if is_state('media_player.bedroom_rpi3_kodi', 'playing') %}
    {% set path = "/local/icons/kodi-playing/" %}
    {% set ext = ".svg"%}
    {{[path,ext]|join("")}}
  {% elif is_state('binary_sensor.ping_bedroom_rpi3', 'off') and is_state('media_player.bedroom_rpi3_kodi', 'off') %}
    /local/icons/kodi-playing.svg
  {% else %}
    /local/icons/kodi-playing.svg
  {% endif %}

Not working there are no icon at all?
