Thank you, works on the Jolt demo site. With real Nifi it doesn't. I am
trying to print those values in ExecuteScript with Groovy script iterating
flowfile attributets:
import org.apache.commons.io.IOUtils
import java.nio.charset.StandardCharsets
import org.apache.nifi.processor.io.StreamCallback
def flowFile = session.get()
def file1 = new File('/home/me/groovy/attributes.txt')
file1.write '##############################################\n'
flowFile.getAttributes().each { key,value ->
file1.append(key+' :')
file1.append(value + '\n')
}
session.transfer(flowFile,REL_SUCCESS)
None of them show up. Is there some way to read them from ExecuteScript?
