Pass output of ListenTCP as a command line argument into ExecuteStreamCommand

Expert Contributor

Hi, I am trying to pass output from a ListenTCP processor into a python code. I have tried passing it in as a command line argument using an ExecuteStreamCommand processor, but had no luck this way, because i had to assign the output an attribute name to pass it as an argument. Is there an alternative way? Thank you.

Parse an output of your processor and assign values to attribute/s. Then in python code your attribute will be available within a flowfile. If this doesn't work for you, please provide more details.

Hi @Ed Berezitsky. I assign the output of ListenTCP an attribute called "request" and pass it into my python code via command line argument as shown here:


However, i get an error saying list index sys.argv[1] out of range.

I know the ${request} is correct because when i send it directly to a putTCP processor, i can view its content, the issue i am having is trying to pass it correctly into my code. Thank you
