Dynamically using testdata based on env in karate framework

I have test data based on environments. Need to use respecitive environment test data for webservice testing in karate framework. So I have config file which load variable based on environment. I have edited my feature file as runtime variable to get the path accordingly something like below. It looks I am missing something or might not using right way.

I have kept testdata based on environment in my folders as like below

TestData
  |->DEV
      |-> applicationFeature_scenorio1_Req.json
  |->SIT
      |-> applicationFeature_scenorio1_Req.json
  |->UAT
      |-> applicationFeature_scenorio1_Req.json
  |->PROD
      |-> applicationFeature_scenorio1_Req.json

Please help me on this how to pick data based on environment.

Config file

dev: {
      baseUrl: 'https://applicationsit.company.com',
      TestData : 'TestData/DEV'
     },
sit: {
    baseUrl: 'https://applicationsit.company.com',
    TestData : 'TestData/SIT'
    },
uat: {
    baseUrl: 'https://applicationuat2.company.com',
    TestData : 'TestData/UAT'
    },
prod: {
    baseUrl: 'https://applicationnewprod.company.com',
    TestData : 'TestData/PROD'
    }
