Same issue here with 2025.2.5

Error "Cannot read properties of undefined (reading 'substr')"

Sometimes after a site reload it appears, but sundently disapers after a short time.

[ZStava]

same issue. Not visible in frontend, not existing card

[estegewr]

Same here. Also tried the workarounf from #97, but it did not work for me!

[zlakes01]

Doesn't work for me either. Is this project live?

[Nico72120]

It's the same thing for me.

Since last update, card does not exist...

[jase0001]

All cards just failed 'custom element does not exist' without any updates being installed, the literally just all disappeared ? Love these cards, hope someone can sort this issue,

[pbranly]

[eddysteurs]

[fenty17]

[SeByDocKy]

Broken for me as well :( :( ..... Pff I am using a lot this card.... Hope fix will appear soon

[fenty17]

Guys, this fix worked for me! #88 (comment)

Some issue to do with lit-element package which you can switch to be loaded locally.

[Lours373]

very strange, came back for me without doing anythings... but 10 minutes later... broke down another time

[Lours373]

As I'm not familiar with this kind of solution...
I tryed the fix mentionned by @fenty17
I proceed as follow :

• Copy all the text of the core lit file in notepad++ and save as "lit-element.js"
• Create folder with studio code server named "lit-element" anf place them as follow

• change the flex-horseshoe-card.js as follow

*/

import {
  LitElement,
  html,
  css,
  svg
  } from "./lit-element/lit-element.js";
  //from "https://unpkg.com/lit-element@2.0.1/lit-element.js?module";

  console.info(
    `%c   FLEX-HORSESHOE-CARD   \n%c       Version 1.2       `,
    'color: yellow; font-weight: bold; background: black',
    'color: white; font-weight: bold; background: dimgray',
  );

• go to paramters, dashboard and click on the 3 dots to add the /hacsfiles/flex-horseshoe-card/flex-horseshoe-card.js?hacstag=20729272514 as follow

• After that "F5" to reffresh

if everything is good, that didn't fix mine.

I've found a solution to this issue.

Try renaming flex-horseshoe-card.js to flex-horseshoe-card.js?ver=1 in your resources list to bypass cache.

EDIT: Solution worked only briefly - same error appeared.

Loading LitElement locally did indeed seem to work permanently.
