Deserialization Does not work with Jackson and Kotlin

[scprek]

I noticed all tests cast the body as a map. So maybe this is a new feature request?

Possible issues, but curious if the databind should be included by micronaut problem at least

zalando/problem#505

zalando/problem#485

zalando/problem#145

Expected Behavior

Without any additional dependencies, I'd expect http client calls with Problem type deserialization to work without Micronaut serde (I'm not sure if micronaut serde works either because switching to it broke too many things, will need to isolate)

Default Problem response

{"type":"about:blank","parameters":{},"status":404,"title":"Test Action does not exist"}

Constraint Violation Problem Response

{"violations":[{"field":"createScheduledAction.scheduledAction.scheduledTime","message":"must be a date in the present or in the future"}],"type":"https://zalando.github.io/problem/constraint-violation","status":400,"title":"Constraint Violation"}

Code

httpClient.toBlocking().exchange(HttpRequest.GET<Any>("v1/scheduled-action/${UUID.randomUUID()}"),
                argumentOf<Any>(), argumentOf<DefaultProblem>()

httpClient.toBlocking().exchange(HttpRequest.GET<Any>("v1/scheduled-action/${UUID.randomUUID()}"),
                argumentOf<Any>(), argumentOf<ConstraintViolationThrowableProblem>()

Note

Spring has ConstraintViolationProblemModule in addition to the ProblemModule()

Actual Behaviour

There are 2 Actual Behaviors based on an extra dependency added.

The Micronaut Object Mapper does not have ProblemModule() Registered. I had to include https://mvnrepository.com/artifact/org.zalando/jackson-datatype-problem/0.27.1

implementation("org.zalando:jackson-datatype-problem:0.27.1")

Default Problem response

{"type":"about:blank","parameters":{},"status":404,"title":"Test Action does not exist"}

Constraint Violation Problem Response

{"violations":[{"field":"createScheduledAction.scheduledAction.scheduledTime","message":"must be a date in the present or in the future"}],"type":"https://zalando.github.io/problem/constraint-violation","status":400,"title":"Constraint Violation"}

Steps To Reproduce

Just so I don't have to parse out the body from the exception, I did this with application-test.yaml. But it does not affect the behavior, I get the same problem either way, this just seems nicer for tests as it feels more like REST assured.

micronaut:
  http:
    client:
      exception-on-error-status: false
