Unable to deserialize session after adding CrawlerSessionManagerValve valve into server.xml

[Spentas]

It works fine before adding CrawlerSessionManager

 com.hazelcast.session.HazelcastSession.deserializeMap Unable to deserialize object in session
 com.hazelcast.nio.serialization.HazelcastSerializationException: There is no suitable de-serializer for type 1633907817. This exception is likely to be caused by differences in the serialization configuration between members or between clients and members.

Hi @Spentas, this exception is thrown when your session object is not configured correctly for serialization on both Hazelcast server and client side. Can you please elaborate more on your case? Was it working fine and then started throwing this exception after some change?
