I know this error has been mentioned more often, but in my case I cannot figure out why I get this.
At first there were no errors
When I look in the developer tools of chrome it get several errors like these:
Failed to load resource: the server responded with https://xxxxxxxx.duckdns.org:xxxxx/local/my-custom-card.jsa status of 404 (Not Found)
I am still running version 0.82.1. and i did not change the resource: they look
I’m in the same position. My Lovelace configuration had previously worked without issue; no changes have been made to it. In the last day or so, I’ve been seeing similar errors:
I’ve updated the button-card.js with the latest version @kuuji provided, restarted HA but still getting the same issue. Everything was fine on monday evening.
I really don’t like that the card depends on the external resource. Is there a way to host lit-element locally on HASS?
Thanks David. I’ve done that in Chrome on windows and now it’s working. My android device is another story. I’ve deleted the storage and site settings for my hass instance but i’m still getting the custom component error.
If I open an incognito tab on my mobile the interface works as expected. Therefore I know it’s not hass related any longer but am i missing something when clearing the cache om my mobile? Any tips are appreciated!
