Question

Hi Team In the below code while I am trying to make custom error response in request filter class when I am returning badRequest it is giving 422 error code But the expectation is 400 Can someone suggest a solution on this ```package com example wiremock stub import java io UnsupportedEncodingException import org apache commons codec binary Base64 import org springframework stereotype Component import com example wiremock errorhandler BadRequestError import com example wiremock errorhandler MockError import com example wiremock errorhandler MockErrorResponse import com example wiremock luukuresponse LuukkuBasicInfoResponse import com fasterxml jackson core JsonProcessingException import com fasterxml jackson databind DeserializationFeature import com fasterxml jackson databind ObjectMapper import com github tomakehurst wiremock common Errors import com github tomakehurst wiremock common Errors Error import com github tomakehurst wiremock common Errors Error Source import com github tomakehurst wiremock common Json import com github tomakehurst wiremock extension requestfilter RequestFilterAction import com github tomakehurst wiremock extension requestfilter StubRequestFilter import com github tomakehurst wiremock http HttpHeader import com github tomakehurst wiremock http Request import com github tomakehurst wiremock http ResponseDefinition import java util ArrayList import java util List Component public class BasicAuthRequestFilter extends StubRequestFilter public String decodeJwt String token throws UnsupportedEncodingException String payload = token split 1 return new String Base64 decodeBase64 payload UTF 8 Override public RequestFilterAction filter Request request if request header Authorization firstValue matches Bearer a zA Z0 9 amp 1 String authtoken = request header Authorization firstValue ObjectMapper objectMapper = new ObjectMapper objectMapper disable DeserializationFeature FAIL ON UNKNOWN PROPERTIES Errors errors String str try String pattern = ^ S 4 75 S 4 $ str = decodeJwt authtoken Token token = objectMapper readValue str Token class String test = token getRepresentation getId if test matches pattern Error error = new Error 400 null response null List lt Error gt listOfErros = new ArrayList lt gt listOfErros add error Errors errorList = new Errors listOfErros return RequestFilterAction stopWith ResponseDefinition badRequest errorList catch UnsupportedEncodingException | JsonProcessingException e e printStackTrace return RequestFilterAction continueWith request return null Override public String getName return Authorization ``` Below is the error snapshot

I am assuming that the endpoint you re invoking isn t the WireMock instance What does your WireMock instance return when you invoke it directly I suspect that there s some transformation happening in the service you re invoking and that that s where the 400 code in the response body comes from Please let me know if my assumptions are wrong

Hi < Bas Dijkstra> Actually the requirement is to have a 400 response only in this case But I am receiving 422 response instead of 400 Let me share the whole code Below is the main stub class in which 2 classes are registered requestfilter and response transformer In request filter class in one of the check I am expecting 400 response but I am getting 422 Below is the main stub class ```package com
