Can't pass argument to Orchestrator using API

Hello,
I Need to pass argument to Orchestrator using API.
argument contains back slash (eg. arg = \11.11.11.1\reports\production.txt)

Here is my code
api_code

and this is the response from orchestrator

How can I achieve this
Thanks in Advance

Hey, I think you should escape each backslash, so this line:
"InputArguments":"{\"file_path\":\"\\11.11.11.1\reports\production.txt\"}"
should become
"InputArguments":"{\"file_path\":\"\\\\11.11.11.1\\reports\\production.txt\"}"
Didn’t work for me though, I got following error
{ "message": "Argument Values validation failed.", "errorCode": 2003, "resourceIds": null }
