Exception error when Projection is called through routing address

Hi All,

I was able to successfully POST a new sales group using Postman. Now, I am attempting to achieve the same using a file.

Integration API used is follows:

This involves placing a JSON file into FTP IN, fetching it through custom routing, and finally directing it to a routing address that calls the same action type projection.

When I perform this process in the CORE system, I encounter the following error

ExecutionException from Sender thread 
Caused by: ifs.fnd.connect.senders.ConnectSender$TemporaryFailureException: Exception while sending data 
Caused by: org.json.simple.parser.ParseException: null

Have you encountered this issue before?
