Having an area with the same name as an entity breaks the dashboard view maintained by home assistant with the error:
Error loading the view strategy:
TypeError: Cannot read properties of undefined (reading ‘toUpperCase’)
There should at least be a warning when naming an area, if that name clashes with an existing entity.
Also described a year ago here.
And a closed-for-lack-of-activity bug report here
Seems like it should be an easy fix and quick to confirm.
In my case I had a hue bulb:
Entity ID: light.hue_white_candle_1_2
Name: Pantry
And an Area:
Area ID: pantry
Name: Pantry
Changing the Name (not Area / Entity ID) breaks / unbreaks the dashboard view.
A simple warning when naming an area would be a good first step.
