Only sometimes: Custom Element doesn't exist: mini-graph-card

Configuration Frontend
1

Hello everyone,

I have one question regarding my UI. I use the mini-graph-card to show the gas price evolution. This seemed to work when I created it. Unfortunately from time to time the card is not shown. Instead there is an error message that the custom element doesn’t exist. But sometimes it is working and the graph is shown but no error message.
How could this happen?

Most of the time it is a browser issue. Try Ctrl-F5 next time and see if that fixes it.

This seems to work for now. I will check the next days if this issue occurs again.

Unfortunately I had the same problem again. A Ctrl-F5 worked again, but I don’t want to do this every day :frowning:

It is a browser cache issue and not a HA issue directly, so you will have to look at the settings in your browser. If you search the forums on browser cache, you should find some helpful information.

It is a browser cache issue, that said I suspect HA is doing something atypical, as this issue happens constantly for HA and very rarely for any main stream web sites.
