Hi guys,

We are currently using smooks in a WSO2 custom message builder/ formatter that will read an EDI file from a folder and sets the WSO2 payload as the transformed xml.

Our WSO2ESB server has been receiving this error intermittently while trying to process larger EDI files using Smooks (30+ lines). Any assistance would be appreciated.

We are currently using:

• org.milyn.edi.unedifact:d01b-mapping:1.4
• wso2esb-5.0.0
• jdk-8u121-linux-x64
• mvel2-2.1.0.wso2v1

ERROR {org.wso2.carbon.connector.util.ResultPayloadCreate} - Error while processing the file/folder {org.wso2.carbon.connector.util.ResultPayloadCreate}org.milyn.SmooksException: Failed to filter source.
