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?
