I'm trying to do a mapping from AWS lambda function response using regex. This is my regex: .*statusCode”:406.*

As you can see - I am trying for it to take a specific mapping from the following response:

{
  "statusCode": 406,
  "body": "{\"aerocrs\":{\"success\":false,\"error_type\":\"request\",\"details\":{\"detail\":\"Incorrect reqyest \",\"errorCode\":4}}}",
  "headers": {
    "x-powered-by": "Express",
    "content-type": "application/json; charset=utf-8",
    "content-length": "116",
    "etag": "W/\"74-Zzo6HU1M1kKkLM9KGtX0jJdePQY\"",
    "date": "Thu, 28 Nov 2019 16:03:05 GMT",
    "connection": "close"
  },
  "isBase64Encoded": false
}

However, I always get to the default mapping. When I change the mapping to .*.*, it gets to the correct one, which makes sense, but for some reason this regex isn't working. Do you have any idea? Thanks!
