I'm testing Spring Boot 4.0.0-RC1 (webflux) and I have problems with basic `ServerRequest.awaitBody&lt;T&gt;()`. It does return an object with correct type but empty (no request data is deserialized). What am I missing?

When calling `awaitBody&lt;String&gt;()` instead, I see the content is read correctly (it's the correct json data). I also see the jackson codec is used to deserialize data, even though I have kotlinx.serialization in dependencies and no direct jackson dependency (but I'm not sure if it is related to my problem).

It seems related. I've managed to exclude `jackson-databind` dependency and my application started to work correctly (I assume with `kotlinx.serialization` instead of jackson)

Unfortunately I can't reproduce the issue in a simple project :disappointed:

But I think I have found the cause. There is no `tools.jackson.module:jackson-module-kotlin` dependency by default in Spring Boot 4. Adding the dependency manually fixes my problem.
