Errors in weather forecast card and not existant files

Hi all,
when i have a look to the debug console while showing my home dashboard i get some errors like in the screenshot.

The “hui-weather-forecast-card.ts:246 Uncaught (in promise) TypeError” ends in the line “if (this._sizeController.value.width === “very-very-narrow”) {”…
where width is not known. This error shows many times…

The …duckdns.org/unknown/src/lit-element.ts 404 (Not Found) only two times.

I’ve no idea and didn’t find anything in the web. Did you have the same errors?
There are no updates available…

Many thanks for your help.
