Wiremock - dynamic mapping of response values

I am attempting to use Wiremock standalone with global response templating to dynamically map an input value (user id) with a response value (username).

My issue in summary is: unable to fetch a value from transformerParameters.* dynamically.

I have this in the response mapping:

{
  "response": {
    "status": 200,
    "headers": {
      "Content-Type": "application/json"
    },
    "transformers": [
      "response-template"
    ],
    "transformerParameters": {
      "usernameMapping": {
        "1": "foo",
        "2": "bar",
        "3": "baz"
      }
    },
    "jsonBody": {
      "id": "{{request.pathSegments.[1]}}",
      "username": "{{parameters.usernameMapping.2}}"
    }
  }
}

My goal is to populate the username field in the JSON response based dynamically on the input user ID, by using the JSON map under transformerParameters.usernameMapping.

I have tried the following for the username field:

I've set up an example repo that quickly recreates my setup and problem, which you can clone from here: https://github.com/francocm/wiremock-template-value-mappings

Am I missing something? I'm trying to avoid writing custom extensions or compiling custom versions of Wiremock, and it feels like I am doing a trivial mistake here.

Thanks

Update - Solution

Use lookup in this manner:

  • {{lookup parameters.usernameMapping userId}}

The git repo has been updated with the working version: https://github.com/francocm/wiremock-template-value-mappings/blob/main/stubs/mappings/example-get-user.json
