Expected Behavior

The health endpoint returns health status and health details

Actual Behaviour

An exception: Unexpected error occurred: Error encoding object [io.micronaut.management.health.indicator.DefaultHealthResult@69164ed1] to JSON: No serializable introspection present for type TaskId. Consider adding Serdeable. Serializable annotate to type TaskId. Alternatively if you are not in control of the project's source code, you can use @SerdeImport(TaskId.class) to enable serialization of this type. io.micronaut.http.codec.CodecException: Error encoding object [io.micronaut.management.health.indicator.DefaultHealthResult@69164ed1] to JSON: No serializable introspection present for type TaskId. Consider adding Serdeable. Serializable annotate to type TaskId. Alternatively if you are not in control of the project's source code, you can use @SerdeImport(TaskId.class) to enable serialization of this type.

The workaround of adding @SerdeImport(TaskId.class) resolves the issue. However, I believe this needs to be fixed regardless

We are facing the same issue, we face the issue when upgrading io.micronaut.kafka:micronaut-kafka to the latest version (5.4.0). Version 4.5.5 seems not include the bug.

Not sure where the bug originates from but perhaps the bug would be best reported in the kafka project: https://github.com/micronaut-projects/micronaut-kafka/issues
