I think I may have found a solution.
I noticed that my data.js wasn’t loading, thus we get this error.
In flower-card.js the location is hardcoded:
import {FlowerData} from '/local/lovelace-flower-card/data/data.js';
So I’ve changed it to point to the location I’ve installed it:
import {FlowerData} from '/local/community/lovelace-flower-card/data/data.js';
The image source should also be changed.
<img src="/local/community/lovelace-flower-card/data/images/${this.config.species}.jpg">
OR you simply install everything in /local/lovelace-flower-card/
This is my resources entry:
- url: /local/community/lovelace-flower-card/flower-card.js
type: module
- url: /local/community/lovelace-card-tools/card-tools.js
type: module
Hope it helps?
