Sensor key not present in dictionary 🤔

[okomen-foreflight]

Hey there! I get this error quite frequently:
Message =The given key 'internal.fleet-consumer-client-stream-thread-3.task.3-3.store.KSTREAM-AGGREGATE-STATE-STORE-0000000013.sensor.put-all' was not present in the dictionary.

_source = "System.Private.CoreLib"
Stacktrace =

Hi @okomen-foreflight ,

Can you share the full stacktrace + your application logs ?
Tanks,

[okomen-foreflight]

Hmm it happens sporadicly so I'm unable to reproduce currently. I will provide you with more information once it happens again and reopen this discussion.
Thanks @LGouellec
