ESB : oracle.tip.esb.console.exception.SchemaValidationException

You deploy an esb project and try to view it via console, and get the following error :


oracle.tip.esb.console.exception.SchemaValidationException: The metadata XML that was processed does not comply with the ESB Metadata XML Schema. Cause: Invalid value '' for attribute: 'executionType'.
If you are manually editing the Import Files, ensure that the metadata is valid and well formed. Otherwise, this is an Internal Error.

Solution :
Add an attribute (executionType="Immediate") to the ESB routing service.
