@Shivansh2407 It certainly requires some investigation. I'm not even clear whether this is a compile-time or execution-time related problem. It might be worth trying the same thing with the JavaScript backend for comparison, since this could be a ergotop only issue.

[jeromesimeon]

Some additional data point. The escaping seems to work fine on the JavaScript backend:

bash-3.2$ cat examples/helloworld/logic/logic.ergo 
namespace org.accordproject.helloworld

contract HelloWorld over TemplateModel {
  // Simple Clause
  clause helloworld(request : Request) : Response {
    return Response{ output: "Hello \"" ++ contract.name ++ "\" (" ++ request.input ++ ")" }
  }
}
bash-3.2$ ./packages/ergo-cli/index.js execute --template examples/helloworld --data examples/helloworld/data.json --request examples/helloworld/request.json 
{"clause":"orgXaccordprojectXhelloworldXHelloWorld","request":{"$class":"org.accordproject.helloworld.Request","input":"Accord Project"},"response":{"$class":"org.accordproject.helloworld.Response","output":"Hello \"Fred Blogs\" (Accord Project)","transactionId":"58f5f261-454e-40d2-8b50-dc40d8aa0641","timestamp":"2019-10-14T18:18:16.564Z"},"state":{"$class":"org.accordproject.cicero.contract.AccordContractState","stateId":"org.accordproject.cicero.contract.AccordContractState#1"},"emit":[]}
