quarkus dev (continous testing) mode fails to report ConstraintViolation - while the same is reported correctly with quarkus test (devservices)

[akil-rails]

I have a pretty straightforward rest-client as follows:

@RegisterRestClient
public interface Client {
  @POST
  Uni<Post> post(@Valid Post request);
}

with a corresponding model

public record Post(
  @NotNull
  Number userId,
  
  Number id,

  @NotBlank
  String title,

  @NotBlank
  String body
) {
  
}

and a test to force a constraint violation

    Post post = new Post(1, 1, "title", null);
    client.post(post).await().indefinitely();

When I run quarkus test the constraint violation is logged in the console

org.acme.ClientTest#test2(ClientTest.java:29) ClientTest#test2() post.request.body: must not be blank [Error Occurred After Shutdown]

But when I run quarkus dev and execution the tests, there's an runtime error that gets reported

2023-05-27 22:10:01,137 ERROR [io.qua.test] (Test runner thread) Internal error running tests: java.lang.RuntimeException: java.lang.RuntimeException: com.fasterxml.jackson.databind.JsonMappingException: HV000116: getParameterIndex() may only be invoked for nodes of type ElementKind.PARAMETER.

I've pushed a repo with the entire project : https://github.com/akil-rails/quarkus-validation

How do I get the quarkus dev mode to report the same exception ?
