Hey! I'm having some trouble setting up my wiremock mapping logic using response templating helpers. I'm trying to understand how to access the request body inside of a

#eq

block - whatever I have setup now is always returning with the false condition. The simplified object coming in is

{
  lender-type: 'installment',
  cuId: '1234'
}

The goal is to use response templating to choose which json file to return. I have these sections in my mapping file:

"bodyPatterns": [{ 
  "mathesJsonPath": "[?($.lenderId == 'installment')]"
}]

and then further down:

"response": {
  "bodyFileName": "{{#eq (jsonPath request.body '$.cuId') '1234'}}respseon_file_A.json{{else}}response_file_B.json{{/eq}}"
}

The

matchesJsonPath

bit seems to work fine as I know I am getting into this mapping file. The problem I'm running into as stated further up above is that when I try to test this logic, the

#eq

block is always returning

response_file_B.json

, no matter what

cuId

field is getting passed. I'm assuming I have some bad character spacing in the handlebars syntax and not to sure how to debug it. Is there anything obvious that I'm doing wrong?

What version of WireMock are you using? With your example, I was able to successfully retrieve file A or file B depending on

cuId

value.

wiremock-jre3-standalone

2.35.0

Hmm… And you’ve restarted WireMock since making those changes?

Yep 😕

Any chance you can give the full mapping and a complete example request body? Might be something going on there

{
  "name": "installment_mapping",
  "request": {
    "method": "POST",
    "url": "/lender",
    "headers": {
      "Content-Type": {
        "equalTo": "application/json"
      }
    },
    "bodyPatterns": [
      {
        "matchesJsonPath": "[?($.lender-type== 'installment')]"
      }
    ]
  },
  "response": {
    "status": 200,
    "headers": {
      "Content-Type": "application/json"
    },
    "bodyFileName": "{{#eq (jsonPath request.body '$.cuId') '1234'}}response_file_A.json{{else}}response_file_B.json{{/eq}}"
  }
}

Was actually about to ask if the full mapping file might help 😂 The request body is

<http://localhost:8080/partner-service/lender>
{
    "firstName": "Danman",
    "lastName": "Mandan",
    "lender-type": "installment",
    "cuId": 1234
}

haha nice! glad you were able to get it sorted 😄

Same 🙂 - thank you for being my rubber duck 😂
