JSON format issue in BPEL 12c

Hi,

I was trying to pass translated string( xml to native json) to a JSON Rest reference created in BPEL 12c but it is failing with a 400 bad request. Have observed that JSON payload sent in the request is containing "/n" new line character and escape characters. How can we fix this?

Steps followed to reproduce this issue:

1)Create a REST reference(without choosing the WSDL interface)

2)Configure the REST bindings with JSON payload in the Request and Response

3)A native schema is created with a sample JSON ( payload to be sent to the REST reference)

4)In the BPEL, two JSON string variables are created for request/response to the REST reference
