Errors while using trigger variables with trigger-based template entities.
kulmegil opened this issue · comments
The problem
Template integration does not provide separate section for variables that would be useful in some scenarios. However it's possible to attach them to individual triggers as described in automation docs.
While trigger and entity works as expected, it spams log with errors

Used it in another scenario and it creates the same error.
Hey there @PhracturedBlue, @tetienne, @home-assistant/core, mind taking a look at this issue as it has been labeled with an integration (template) you are listed as a code owner for? Thanks!

The same error but in automation with trigger variables. Error appears not every time trigger fires. Can't find the pattern of its occurrence.
Core 2022.5.5
HA OS 8.1
Seeing same issue in 2022.8.6. In this case the trigger causing it is:
- platform: event
event_type: event_template_reloaded
variables:
version: >
{% set version = [state_attr('sensor.tessie_vehicle_state_data_sensor', 'car_version'),states('sensor.tessie_software_teslascope'),states('sensor.tessie_software_current_version')] | reject('in',[None,'unknown','unavailable']) | list | first|default('unknown') %}
{{ version.split(' ')[0] }}
If I remove that event and reload I get no error. Mind, issue clearly is not specific to this kind of trigger; just that this trigger is triggered on reloading the templates.
