Describe the issue you are experiencing

I'm new to using templates and I was trying to add a condition to limit an automation to run at most once daily.

Testing various other triggers in the UI appears to work with a popup green or yellow box indicating whether the automation succeeded or failed.

But nothing happens when clicking "Test" to testing the template:

I assume I'm doing something wrong but I expect at least an error message. I don't see anything in the console.

I've included a screen recording of the issue.

Version info:

Home Assistant

Core 2024.5.2
Supervisor 2024.05.1
Frontend 20240501.1

Describe the behavior you expected

Expect to see a popup when clicking on the Test button for a trigger while debugging.

Steps to reproduce the issue

1. Try to create an automation and enter a template trigger with the value {{ true }}
2. Click Test on the drop-down menu for that trigger
3. Nothing happens. Expect to see a popup with an error or success message ...

Hmm working for me. Did you really try in safe mode? It's clear that your screen grab is not from safe mode.

The yaml editor for template automations or scripts is broken.

When I try: service: media_player.play_media data: media_content_type: folder media_content_id: {{ ["2023", "2024"] | random }} target: entity_id: media_player.mpd_homeassistant

Then it does not work.

When I try: service: media_player.play_media data: media_content_type: folder media_content_id: >- {{ ["2023", "2024"] | random }} target: entity_id: media_player.mpd_homeassistant

Then it works.

Where are many more examples like that.
