[BUG] Default value is not recognized at controller end while using spring openapigenerator

below is my openapi spec

get:
  summary: Get User By Id
  operationId: getUserById
  parameters:
    - in: query
      name: id
      description: Unique Id of an User
      schema:
        type: integer
        default: 10

I am using spring openapigenerator to generate interface API code which will be implemented in controller using below configurations in build.gradle,

def swaggerSourceFile = "$projectDir/src/main/resources/api.yml"
def swaggerTargetFolder = "$projectDir/src/generated/java"
def swaggerConfigFile = "$projectDir/swaggerConfig.json"

openApiGenerate {
    generatorName = "spring"
    configFile = "${swaggerConfigFile}".toString()
    inputSpec = "$swaggerSourceFile".toString()
    outputDir = "$swaggerTargetFolder".toString()
    globalProperties = [modelDocs: "false", apiTests: "false", apiDocs: "false"]
    generateApiTests = false
}

and my swaggerconfigFile has below configs,

{
    "interfaceOnly": true,
    "library": "spring-boot",
    "useDefaultValue": true,
    "dateLibrary" : "java8",
    "typeMappings" : {
	    "OffsetDateTime":"Instant"
    },
    "importMappings" : {
	    "java.time.OffsetDateTime":"java.time.Instant"
    },
    "useGzipFeature" : true,
    "useRuntimeException" : true,
    "apiPackage" : "com.api",
    "modelPackage"  : "com.api.model",
    "modelNameSuffix" : "DTO",
    "sourceFolder": "",
    "useBeanValidation" : false,
    "performBeanValidation": false
}

Here default value for the input is configured as 10 and its also available in generated API interface given below, but while accessing the API, controller don't recognize the default value and it got null if no data provided for input.

Generated Interface API code:

 @RequestMapping(
        method = RequestMethod.GET,
        value = "/user",
        produces = { "application/json" }
    )
    default ResponseEntity<UserDTO> getUserById(
        @Parameter(name = "id", description = "Unique Id of an User", in = ParameterIn.QUERY) 
        @RequestParam(value = "id", required = false, defaultValue = "10") Integer id
    ) {
     }

Start with the OpenAPI parameter in api.yml, the spring generator configuration in build.gradle and swaggerConfig.json, and the generated API interface shown in the report. Reproduce the generated controller behavior when id is omitted, then trace the spring generator's handling of defaultValue. Done means the generated endpoint consistently exposes and applies the declared default value, with a regression test covering the case.
