'Wiremock Placeholder isn't recognized

I tried with the following json but the wiremock doesn't recognize my change. I read the documentation of wiremock and I saw that they said: JSON equality matching is based on JsonUnit and therefore supports placeholders. I also tried with both JDK 8 and JDK 13 but both are not working

Below is the detail

    "method" : "POST",
    "bodyPatterns" : [{
      "equalToJson" : {
        "recipient": {
           "address": {
              "city": "Bellevue",
              "postalCode": "52031",
              "countryCode": "US"
           }
        },
        "sender": {
           "address": {
              "city": "",
              "postalCode": "",
              "countryCode": "HK"
           }
        },
        "shipDate": "${json-unit.any-string}",
        "accountNumber": {
           "key": ""
        }
      },

Result when running selenium test with mock (I executed mock via java -jar tmp/wiremock.jar --global-response-templating --root-dir ./mock --port 1337 ):

                                                           |

Can anybody make some suggestions here. Thank you for reading my question

Solution 1:[1]

you have to enable the placeholder as below and you should make sure you are using the jre-standalone jar. you seem to be using the normal standalone jar

"enablePlaceholders" : true

Solution 2:[2]

The usage of "${json-unit.any-string}" is right. But placeholder works when the right dependency is used.

Using dependency com.github.tomakehurst:wiremock-jre8 worked for me.

Refer https://wiremock.org/docs/request-matching/ for more info. This would mention the following note

Placeholders are only available in the jre8 WireMock JARs, as the JsonUnit library requires at least Java 8.
