In 2025.11 visual editor for History Graph doesn't show entities if one of them is non existent #27857
Description
Checklist
- I have updated to the latest available Home Assistant version.
- I have cleared the cache of my browser.
- I have tried a different browser to see if it is related to my browser.
- I have tried reproducing the issue in safe mode to rule out problems with unsupported custom resources.
Describe the issue you are experiencing
After update to 2025.11.0 and editing existing History Graph in Dashboard, list of used entities is completely hidden if there is one that's non-existent. Deleting it in YAML will start rendering the visual editor correctly
Describe the behavior you expected
List of entities in the graph should be visible even if one is non-existing (has been removed for example, after the graph was configured)
I am pretty sure it used to work before the update.
Steps to reproduce the issue
- create history graph with some entities on dashboard
- delete one of the entities
- open history graph configuration page
- puff... no entities listed at all... only editable via YAML (code editor)
