Hi Bekker, Thanks for the response. Find below the code I am trying to work on, which is a modification of the code you shared. I am trying to take the output/flowfile from previous processor (which is a JSON) and trying to convert it to XML flowfile. Please help identify where I am wrong. Code: import net.sf.json.JSON
import net.sf.json.JSONSerializer
import net.sf.json.xml.XMLSerializer
import java.nio.charset.StandardCharsets
JSON json = JSONSerializer.toJSON( session.get() )
XMLSerializer xmlSerializer = new XMLSerializer()
xmlSerializer.setTypeHintsCompatibility( false )
newFlowFile = session.write(session.create(), {outputStream ->
outputStream.write(xmlSerializer.write( json ).getBytes(StandardCharsets.UTF_8))
} as OutputStreamCallback)
session.transfer(newFlowFile, REL_SUCCESS) Error: 06:03:44 EDT
