Konfigureringsflödet kunde inte laddas: 500 Internal Server Error Server got itself in trouble

[SSungam]

Hi, I get this error message when trying to config the sensors:
Konfigureringsflödet kunde inte laddas: 500 Internal Server Error Server got itself in trouble

Have rebooted, re-installed the integration, but same issue remains. Any ideas?

I have made a PR that fixes this.

Its related to an recent update from home assistant where they made config_entry read-only.
