Corda White list Exception - corda

Question

I tried to manually add "org.hibernate.AnnotationException" to the whitelist. I tried to implement serializationWhitelist interface in my state class.
lets say my state class is of type Person and has Address type defined inside it. Every time I try to get the states out of the vault I get this error. or another for "org.hibernate.MappingException". Also When my state implements QueryableState I'm not even able to persist the data. and get the below error

Answer 1

Your flow is throwing various exceptions because of underlying issues with your code. Corda is then trying to serialise these exceptions to send them back to your RPC client via the RPC framework. Since these types are not whitelisted to be sent via RPC, you get a Kryo exception when you try.
In other words, these exceptions are just a symptom (of your underlying code throwijng AnnotationException or MappingException) rather than a root cause.
Can you post the code showing the Person state definition and how you are trying to retrieve it from the vault in the flow?
