How to print one of the attribute value from JSON payload to response body?

[#1]

Scenario: I need to print one of the attribute value from JSON payload from 'Query parameter' to response body.

Example: In the payload it is given:

"site": {
"name":"abc demo"
}

So in this case i need to print the name value that is 'abc demo' in response body.

Issue: I wrote code but it is giving below error:
"message": "Cannot read property \"name\" from undefined",

Script:

(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {


var requestbodydata = request.queryParams.input[0];
var test = requestbodydata .site.name;

return(test);

}

Any idea how to solve this?

Hey,

You have a spcae:

var test = requestbodydata .site.name; remove this, it should work

Hi Aman.

In the actual script there is no space.

Do one thing:

var requestbodydata = JSON.parse(request.queryParams.input[0]);
return requestbodydata.site.name;

getting error:

"error": {
    "message": "Expected end of stream at char 6",
