Hi,
In our production environment we sometimes have NPE which originates from the Neo4jPersistentEntityImpl class. It appears that the variable named storedType is null when the matchesAlias
method is being invoked. See the stacktrace below:
We're currently using version 2.1.0. Is this something that has been fixed in version 2.2.1?
Kind regards,
David
