Describe the issue you are experiencing

On several of my automations, when I need to troubleshoot it, I find myself with an empty "Trace Timeline". I can see the steps details, download the trace in json format but the "Trace Timeline" tab is empty.

It seems to happen more frequently when using a repeat, while. Here's the most basic automation I've been able to write that causes this issue.

alias: New automation
description: ''
trigger: []
condition: []
action:
  - repeat:
      sequence:
        - stop: test
      while:
        - condition: state
          entity_id: input_boolean.test
          state: 'on'
mode: single

It seems to happen more frequently when using a repeat, while. Maybe it's backend related, but I'll report it here since the automation works and the trace is generated for download.

Describe the behavior you expected

See the trace timeline as with any other automations

Steps to reproduce the issue

Write a new automation using the UI with a Reapeat/While
Add a stop action
Run
Check the "Trace Timeline". It should be empty

It could also be related to this issue as well. https://github.com/home-assistant/frontend/issues/15348

I do see this is throwing exceptions which is why it is not rendering. Couldn't quite figure out how this code is structured though.

It looks like a backend issue, since the trace marks the entity id as an action. That's also what the error is about. Need to look further into this how it works.
