Custom element doesn't exist: check-button-card.

[codeclinic]

HASS Version: 0.114.4
Check Button Card Version: 1.2.0

I've been using check button card for a long time now but in the last couple of days it stopped working and now I just get red boxes with "Custom element doesn't exist: check-button-card." wherever the checkboxes should be displayed.

I'm using layout-card for my ui-lovelace cards and recall another HACS addon having similar issues in the past. I can't remember which one it was or what the fix was but do remember it was related to the addon entity needing a slight code change.

I am also getting this message, but with 0.114.4 and CBC card version 1.2.0 but I am using YAML mode and I'm not using layout card on this particular page. Typically, when adding any custom card I have added the resource for it in YAML, then run a reload resource and double checked if it was in the UI resources panel. Not finding any references to resources in any of the instructions, forum threads or issues, I have tried adding it as:

- url: /hacsfiles/check-button-card/check-button-card.js
  type: module

and

- url: /hacsfiles/check-button-card/check-button-card.js
  type: js
      

neither of which seems to work. Could this be related? I'm not seeing anything that appears to be related in the logs. I checked the Chrome console log and found this, if it helps:
/hacsfiles/check-button-card/check-button-card.js:739 Uncaught SyntaxError: Unexpected token 'export'

I've only added this card today, so for me it has never run correctly yet. Also, I have a working MQTT setup with discovery enabled and I'm using the proper discovery_prefix for my setup.

And just like that... it's working. I changed from back from type: js to type: module but that's the only change I made. I'd tried module first and it didn't work so I'm not sure what happened.

It's still not working for me.

seems like same issue like #17 - maybe same solution applies?
