Cannot read properties of null (reading 'shadowRoot') #84

[Mariusthvdb]

please see the original issue at Maykar's repo maykar/kiosk-mode#84

will you be able to 'clone' these issues too? and, if yes, be willing to see what can be done to prevent this from happening?

Sincere hopes (and thanks btw!) you can maintain the repo, because it was too nice to not keep up with current Dashboard

keeps showing in the log, not exactly sure when or why any user action causes this.
please have a look?

I also have this popping up. I tried adding kiosk-mode to my config.yaml file but didn't change anything.

is this still happening? tbh, I dont see them anymore. Otoh, I got so fed up with frontend errors in the HA log, I filtered those with:

  frontend.js.latest: fatal

so, if someone will confirm, we can close?

Hey @Mariusthvdb,
I wanted to ask the same because I had something in mind if this was still happening.
Maybe it got solved with the latest changes that I did.
Let‘s left it open for some days to see if someone else responds, if not it can be closed.

Hi @Mariusthvdb,
Could you check one more time if this error is showing for you in your logs?
Regards

[Mariusthvdb]

sure, as I said above, I dont see these anymore, but I've filtered the errors to 'fatal'

I'll restart using no filter and check again

update

no more, so lets close!
thanks for you ongoing efforts !
