Hi! I am using kotlinx.serialization and am running into some issues with regards to generic values in data classes. I have roughly the following:

@Serializable
data class BaseResult<T>(val data: T, val foo: Int)

@Serializable
data class SomeData(val bar: String)

// Then when decoding incoming json I do:
val response = Json { ignoreUnknownKeys = true }
    .decodeFromString<BaseResult<SomeData>>(responseBody)

When doing this I get the following error:

Serializer for class 'SomeData' is not found.
kotlinx.serialization.SerializationException: Serializer for class 'SomeData' is not found.
Mark the class as @Serializable or provide the serializer explicitly.

you usually don’t need pluginManagement{}, just put the plugin into a plugins{} block at the top of the build file. For multi-module projects, only put the version number in the root build file (with “apply false” if the root project has no code)
