The first step is InvokeHTTP processor to make a REST API call and receive a JSON response.&nbsp; I have used "Put Response Body In Attribute"&nbsp; to store the JSON response into an attribute.</P> <P>2. The next step is ExecuteStreamCommand processor to invoke Python script and&nbsp; passing the JSON response attribute from previous step as an input argument.&nbsp; The Command Argument passed to the processor is:</P> <P>/home/kavipriya/script/Scaling.py;"${AssetModel}";</P> <P>&nbsp;</P> <P>I am able to read the JSON message within my python script, but the double quotes within original JSON message are removed by Nifi and I get following error when parsing the JSON message:</P> <P>&nbsp;</P> <P>"json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 3 column 5 (char 10)"</P> <P>&nbsp;</P> <P>Can someone tell me why are the double quotes removed when JSON message passed as argument and also if there is an option to retain the double quotes.&nbsp; Thanks for your help!</P> <P>&nbsp;</P> <P>I have attached the screenshots and also the JSON message passed to python script and also the python logs showing double quotes missing when reading the argument.</P> Tue, 01 Oct 2019 12:42:47 GMT Nifi1 2019-10-01T12:42:47Z
