ExecuteScript in nifi

[#1]

I am trying to get the data from elasticsearch from processor group via port. I want to apply some python code on the output data. How can I read the input and execute the code?

Solution is to use ExecuteStreamCommand option. The reason is ExecuteScript in nifi is not pure python instead it's jython. So, to execute a python code, we only need to set the python path and the file path. The configuration for this can be seen from the image attached below.
