QUESTION: How to copy (behavior) integer value from path to body field?

[VVasyaev]

Expected behaviour

{
    "id": 1,
    "word": "some"
}

Actual behaviour

{
    "id": "1",
    "word": "some"
}

Steps to reproduce

1. POST /imposters

   {
   "port": 21130,
   "protocol": "http",
   "stubs": [
       {
           "predicates": [
               {
                   "matches": {
                       "method": "GET",
                       "path": "/files/\\d+/info"
                   }
               }
           ],
           "responses": [
               {
                   "is": {
                       "body": {
                           "id": "${prod_id}",
                           "word": "some"
                       }
                   },
                   "behaviors": [
                       {
                           "copy": {
                               "from": "path",
                               "into": "${prod_id}",
                               "using": {
                                   "method": "regex",
                                   "selector": "\\d+"
                               }
                           }
                       }
                   ]
               }
           ]
       }
   ]
   }

2. Call mocked URL: GET http://localhost:21130/files/1/info

Software versions used

OS         : Ubuntu 22.04.1
mountebank : 2.8.1

Log contents in mb.log when running mb --loglevel debug

Not sure if log needed for this case.

I need to have an integer value in the response body but can't use ${prod_id} without quotes because it brokes json structure.

Regex by default outputs all matches as string, if you want an integer you can add a custom injection script that would execute regex against path and parse output of it using parseInt('123')
