A particular flow is working manually but when replaying the script, seeing 500 error in one transcation at a particular request.
Its giving this message
giving javax.servlet.ServletException: Possible CSRF attack noted when comparing token in session and request header. Request: POST

Could someone please provide solution to this, The application is hosted in AWS ?
