In my Compose/Kotlin Multiplatform project, I have a `@Serializable` data class with `kotlin.uuid.Uuid` as one of its properties. I'm using Kotlin 2.0.21-RC and Kotlinx-Serialization 1.7.3, but I get the following compilation error:
```Serializer has not been found for type 'kotlin.uuid.Uuid'. To use context serializer as fallback, explicitly annotate type or property with @Contextual```
From what I understand, there is now a built-in `kotlin.uuid.Uuid` serializer in Kotlinx-Serialization according to the following PR:
<https://github.com/Kotlin/kotlinx.serialization/pull/2744>

Is there any particular setup I need to do to make it work?

While there is a serializer provided in the runtime, the kotlin plugin does not generate code using the serializer the until 2.1.0. you can either upgrade Kotlin or just contextual and setup the serializer in the serializer module  

Thanks for the explanation and for your help. Upgrading to Kotlin 2.1.0-Beta1 fixed the problem! Now the code is fully compilable and working, although Android Studio LadyBug (2024.2.1) still shows them as error (serializer not found, etc).
