Integration stopped working ("invalid config") after update to 2022.9.x

As the title suggests, the integration stopped working here. It still works on my 2022.8.9 installation, though, so I guess 2022.9 broke something.

I updated home assistant and browser mod, but because i didnt want to redo all the popups rn i installed a backp from 2 days ago. Now the miele integration refuses to work even with 2022.8.7

Same here

It still works on my test installation (snap install on ubuntu server) with 2022.9.1.

It still does NOT work on my main installation (Home Assistant Operating System, v2022.9.2).

Sorry, same as #129.

However, I was able to get it running again:

Someone suggested that adding the cache path helped.

miele:
  client_id: !secret miele_client_id
  client_secret: !secret miele_client_secret
  cache_path: /config/.storage/.miele-token-cache

Since I un- and reinstalled it several times, this might have been it.

EDIT: And then again, maybe not. I removed the line and it's still working as expected.

Since this is a duplicate and I have no idea what fixed the issue, I'm gonna close it.
