Hi LuisMa,
To write code here you need:
1 Wrap code with "<pre" tag.
2 Replace all < chars with <
Test tab does not affect with generic security context.
You need to reinit your service response with actual JSON .
So:
1 use this code to log, and copy actual JSON from console:
pre
console.log(JSON.stringify(response))
/pre
2 Open service "Test" tab.
2.1 Paste JSON to "response" area.
2.2 Click on "Import as response".
Details:

After your response parameters will change to actual response from JSON. And you will be able to use these parameters in mapping.
Regards.
