Wiremock not detecting POST body request by Spring 6 RestClient

[rana2884]

Proposal

I am trying to use Wiremock to test RestClient requests released recently in Spring 6.1. I am facing issue only in the case of restClient making POST request with body which wiremock fails to detect showing message "body does not exist" so not able to mock the expected response to the request. E.g.

restClient
                .post()
                .uri("/todos")
                .contentType(MediaType.APPLICATION_JSON)
                .body(panResponse)
                .retrieve()
                .body(String.class);

Wiremock stub:

wireMockServer.stubFor(
                WireMock.post("/todos")
                        .withHeader("Content-type", equalTo("application/json"))
                        .withRequestBody(
                                equalToJson(objectMapper.writeValueAsString(panResonse)))
                        .willReturn(WireMock.aResponse().withStatus(200).withBody("Hello")));

Reproduction steps

Make a POST request with request body with RestClient and try to mock it with wiremock, it will show message "Body does not exist."
