Type conversion when using bodyAsJson

Description:

Wiremock changes data types in response fields.

For example: I have following response template:

[
  {
    "Guid": "77ae335b-5d79-42dc-8ca7-236280ab9111",
    "Request": {
      "Path": {
        "Matchers": [
          {
            "Name": "WildcardMatcher",
            "Pattern": "/hello"
          }
        ]
      },
      "Methods": [
        "post"
      ]
  },
  "Response": {
    "StatusCode": 200,
    "BodyAsJson": { 
      "text": "{{request.bodyAsJson.text}}"
    },
    "Headers": {
        "Content-type": "application/json"
    },
    "UseTransformer": true
  }
}
]

If I am making request with field that containts text then wiremock send my text back as string type as it should be: "text": "abc" - > "text": "abc" but if I am making request with field that contains string but it is a number then wiremock responses with the Int type: "text": "1" -> "text": 1

Expected behavior:

Wiremock does not change data types in response fields.

Test to reproduce

1. Use template from example
2. Create request with string that contains number (for example: "test": "1")
3. Wiremock sends back response - "test": 1

Hello @v1le thank you for this issue. I’ll investigate.

(Note that I first thought that this could be related to Handlebars: https://dotnetfiddle.net/b3WCwx, but I think that’s ok.)

I see that Scriban does have the method Evaluate which will return the real value, so an int stays an int.

See this example: https://dotnetfiddle.net/sZGbaX

However, currently I’m using the Render method, also for Scriban.

So in order to get this working, I need to add a new setting which can switch between Evaluate or Render and then you need to choose Scriban instead of Handlebars.

Maybe this could work, however I’ll not build this in a short time…
