Blueprint automation saved succesfully but not appears in UI


today I created my first blueprint template (copying the yaml file in /HomeAssistant/blueprints/automation). The UI show it.

I created a new automation with this blueprint, but after save it succesfully, it not appears in a automation list in the UI (yes in the automation.yaml file).

In the HA log appears:

ERROR (MainThread) [homeassistant.components.automation] Blueprint Controla temporitzador interruptor generated invalid automation with inputs OrderedDict([(‘switch’, OrderedDict([(‘entity_id’, ‘switch.xxxxxxx’)])), (‘timer’, ‘timer.temporitzador_llum’)]): expected a dictionary for dictionary value @ data[‘action’][0][‘target’]. Got None

I don’t know the reason. Anybody could you help me please?


PD: I have the latest docker version.
