Unable to preload CSS

[errormastern]

What happened?

Hi together,

I've been getting this error more frequently lately. It seems to happen after I've been navigating around the Home Assistant frontend for a while. Unfortunately, I can't reliably reproduce it.

Also, I can't download the file mentioned in the error message from the Z2M frontend—the link just redirects back to the Z2M frontend.

Is there another way to get the state.json.zip file so I can provide it here?

I'm using v 1.40.0-1 (currently no dev branch available - 1.40.0-dev same behavior)

Cheers, Stefan

Did you download state.json.zip?

I will not attach state.json.zip
