I have added the "Resources" line in the Raw UI still getting this error :(

Hey, did you download the bundle and place it inside your home assistant www/ folder?
If so navigate to http://[HA-IP]:[PORT]/local/mini-graph-card-bundle.js to see if it's served properly.
I really recommend checking out HACS which really simplifies the install/update process of custom cards.
I have installed the plugin from HACS and it also fails.

What happens when you navigate to http://[HA-IP]:[PORT]/local/community/mini-graph-card/mini-graph-card-bundle.js?
And what browser are you using?

All is ok when I navigate to url http://[HA-IP]:[PORT]/local/community/mini-graph-card/mini-graph-card-bundle.js
@kalkih I tried via HACS still getting the error!

Double check your resource reference, if installed through hacs it should be
- url: /community_plugin/mini-graph-card/mini-graph-card-bundle.js
type: module
It's working fine @kalkih
My mistake! Forgot to add "resources:"
Have the same problem.
My resources url
/hacsfiles/mini-graph-card/mini-graph-card-bundle.js
Installed with HACS
Seems to be working in inkognito mode.
Clear browser cache or try pressing the three dot menu in the Home Assistant header and then press "reload resources".
