Why doesn't micronaut show a stacktrace for error

[SZanko]

I have a Dto with a java.time.Duration

@Introspected
@Serdeable
public record TourDto(
        String id,
        String name,
        String description,
        String startDestination,
        String endDestination,
        TransportType transportType,
        Double distance,
        @JsonProperty("estimatedTime")
        @JsonDeserialize
        @JsonSerialize
        Duration estimatedTime,
        //List<TourLogsDto> logs,
        String routeInformationPath) {
}

when I try to use it in a post as a param:

    @Post(uri = "/", produces = MediaType.APPLICATION_JSON)
    public HttpResponse<TourDto> createTour(@Body TourDto tourDto) {
        final TourModel toBeSaved = tourMapper.convertToModel(tourDto);
        toBeSaved.setId(null);
        final TourModel saved = tourRepo.save(toBeSaved);
        return HttpResponse.created(tourMapper.convertToDto(saved));
    }

with this body:

{
        "id": "",
        "name": "name",
        "description": "description",
        "startDestination": "startDestination",
        "endDestination": "endDestination",
        "transportType": "DRIVING_CAR",
        "distance": 0,
        "estimatedTime": {
                "units": [
                        {
                                "duration": "#/components/schemas/Duration",
                                "durationEstimated": false,
                                "dateBased": false,
                                "timeBased": false
                        }
                ],
                "zero": false,
                "negative": false,
                "seconds": 0,
                "nano": 0
        },
        "routeInformationPath": "routeInformationPath"
}

it produces

{
  "_links": {
    "self": [
      {
        "href": "/api/v1/tour",
        "templated": false
      }
    ]
  },
  "_embedded": {
    "errors": [
      {
        "message": "Failed to convert argument [tourDto] for value [null] due to: Unexpected token START_OBJECT, expected VALUE_NUMBER_INT \n at [Source: REDACTED (`StreamReadFeature.INCLUDE_SOURCE_IN_LOCATION` disabled); line: 9, column: 23]",
        "path": "/tourDto"
      }
    ]
  },
  "message": "Bad Request"
}

my build.gradle.kts specifies however that jackson is used:

    annotationProcessor("io.micronaut.serde:micronaut-serde-processor")
    implementation("io.micronaut.serde:micronaut-serde-jackson")
    implementation("com.fasterxml.jackson.dataformat:jackson-dataformat-csv")
    implementation("com.fasterxml.jackson.core:jackson-databind")
    implementation("com.fasterxml.jackson.datatype:jackson-datatype-jsr310")
    implementation("com.fasterxml.jackson.datatype:jackson-datatype-jdk8")

can someone help me pls and explain me why this stuff happens?

We don't print stack traces by default for this kind of user error to avoid DoS or info disclosure vulnerabilities. You may be able to enable to stacktrace printing by messing with your logback config.

Your dependency setup will use micronaut-serialization based on jackson-core. It will not use jackson-databind. For that you would need to remove the io.micronaut.serde dependencies and instead add micronaut-jackson-databind.

From the error message, it looks like the weird Duration data structure is not recognized. Micronaut-serialization expects something like "PT1H", not a whole json object.
