Then one of the cards you are using is reusing code from button-card without having changed it.

Grep all your cards from your shell and look for button-card-action-handlerin all those files.

I have exactly the same issue with 'mod-card'. I definately haven't declared it twice.
The issue appears in all dashboards.
Searched for mod_card in all my files but havent found an entry. Did you solve the issue?
I'm using edge as browser but it happend in Chrome as well. AFAIK it is anyway the same core.

[Pirol62]

Hi @johntdyer . Did you solve the issue? If yes, what did you do?
I do not really understand what RomRider wrote.

[Pirol62]

Hi all. I solved the issue for myself. home-assistant/frontend#11494
I hope it may helps some others as well.

Hello,
Having the same issue, double checked ally my custom_components:

It's only used in the button-card file.

Edit:
I just found out that it is coming from Dwains_Dashboard :/

[LiivaneLord]

Go to Overview -> Edit dashboard -> Manage dashboards -> Resources. There should be 2 lines. I deleted mine from /hacsfiles folder and kept file in the /local folder.

Idk is it correct, but I have no error anymore and charts are working. Btw, I got this error only with firefox. Chrome or edge didnt cause the error.
