After the migration to OH3 I have this one line that keeps coming back now and then in the openhab.log
2020-12-28 21:09:15.648 [WARN ] [e.internal.SseItemStatesEventBuilder] - Attempting to send a state update of an item which doesn't exist: undefined
I have not found any logic so far in when it happens. I don’t have any other errors in the logs.
Is there a way to debug this further as to know which item could be gone missing ?
