Hi [~dwysakowicz]
After upgrading to 1.14.4, we are facing another issue when restoring the state
with the deleted field :
NPE has been corrected, but we have another exception :
Caused by: java.lang.IllegalStateException: field serializer snapshots should
be present.
when restoring the fields serializer of the POJO
Full stack :
java.lang.Exception: Exception while creating StreamOperatorStateContext.
