NiFi ExecuteScript - Able to add attributes to created FlowFiles?

avatar
New Contributor

Hi all, I am passing a FlowFile with several custom attributes to my ExecuteScript processor (running python). I want the ExecuteScript to create two new FlowFiles, each having their own set of attributes (the values are to be retrieved from the input FlowFile). Problem is, I am unable to add any attributes to the two new flowfiles and it throws the error "org.apache.nifi.controller.repository.StandardFlow" object has no attribute "putAttribute"

 

flowFile = session.get()
if flowFile != None:
    ...
    destFlowFile = session.create(flowFile)
    # doesn't work
    destFlowFile.putAttribute(destFlowFile, "logMsg", "Testing Msg")
    destFlowFile.putAllAttributes(destFlowFile, backupAttributes)

 

 I've followed the examples listed in this guide https://community.cloudera.com/t5/Community-Articles/ExecuteScript-Cookbook-part-1/ta-p/248922, hence I wasn't expecting this to not work. Is it just not possible to add attributes to created FlowFiles and if so, are there any alternative methods? Thank you!
