Thanks. I had found an online article that outlined creating ui-lovelace.yaml and editing .storage/lovelace_resources but I was reluctant to start changing formats of hidden files.
My problem was basically that I had started using Home Assistant before Lovelace and the early iterations of Lovelace were configured in ui-lovelace.yaml. Deleting that file let me just use the Lovelace UI.
There is probably more to it than that- read the whole thread.
I’ve seen this error in my log a few times.
I’m new to HA and confused.
I have one HACS card installed, that is numbercard-box
I have the following (and only lovelace entry) in my configuration.yaml:
lovelace:
resources:
- url: /hacsfiles/numberbox-card/numberbox-card.js
type: module
