We are facing the same issue, we face the issue when upgrading 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 |

## Summary This pull request addresses issue #1026 by implementing a custom `Serde<TaskId>` to kafka-streams module. This avoid a serialization error when calling the `/health` endpoint, which throws in turn a: ``` 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. ``` ## Changes Made - Added serde processor as `annotationProcessor`, and serde api as `compileOnly` to load in the annotation. - Created a class dedicated to adding annotation for external classes that need serialising as part of the health result ## Related Issues - Fixes #1026

Actual Behaviour
An exception:

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.
