Error when running locate change set in 4.0.5 client.

Hi,

I am trying to locate change set in stream in RTC 4.0.5 client, but  i am ending up with below error message.

"ScmWorkItem: Deserialization failed: System.Runtime.Serialization.SerializationException: Element ':item' contains data from a type that maps to the name 'com.ibm.team.scm.rich.rest.dto:ScmChangeSetLocationsEntry3'. The deserializer has no knowledge of any type that maps to this name. Consider using a DataContractResolver or add the type corresponding to 'ScmChangeSetLocationsEntry3' to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding it to the list of known types passed to DataContractSerializer."

Regards,
Mohan.
