I have a template light depending on another template binary sensor.
The former entity generates an error whenever template entities configuration reloads.
Traceback (most recent call last):

The problem only happens when loading and it works any other time.
I have added event_template_reloaded trigger but it does not work.
How could I update the template to avoid the error message?
Here is the simplified configuration of both template entities:
- platform: template
lights:
bedroom_light_effect:
value_template: "{{ states('light.bedroom_light') }}"
effect_list_template: "{{ state_attr('binary_sensor.light_effect', 'options') }}"
effect_template: "{{ 'Holiday' if is_state('binary_sensor.light_effect','on') else 'Nothing' }}"
- trigger:
- id: other-triggers
...
- id: reload
platform: event
event_type: event_template_reloaded
binary_sensor:
- name: Light effect
state: "..."
attributes:
options: "{{ ['Nothing', 'Holiday'] }}"
