Issue : DataHub upgrade from 6.2.0.2 to 6.5.0.2 while keeping Hybris at 6.2.0.2.

Hi Team, I have successfully upgraded DH from 6.2.0.2 to 6.5.0.2 while keeping the Hybris @6.2.0.2 , using the hybrid adapter. And it is working fine in my local, but unfortunately in my DEV ENV I see below exception, could you please help me with the root cause?

An error occurred during the export of impex file{ java: { exception: "com.hybris.datahub.api.publication.PublicationException" }, syslog: { severity: "Informational", appName: "consolelogfile", host: "novar01-01-AZ0-pharma-myalcon-dev1-datahub", priority: "134", facility: "local use 0", timestamp: "2017-11-20T12:14:26.712474+00:00" } } 2017-11-20 17:44:10.322
