This does not seem to work and is throwing Serializer for class 'ApiResponse' is not found

@Serializable
data class ApiResponse<T>(
    val result: T? = null,
    val error: ApiError? = null
)
call.respond(ApiResponse(result = gameEngine.newGame()))

Please help.
Json.encodeToString(..) works fine.
ktor config:

fun Application.mainModule() {

  install(ContentNegotiation) {
    json()
  }
  ...
}

Using ktor 1.4.1 and serialization 1.0.0

Have you added kotlin("plugin.serialization")  into build.gradle(.kts) file?
It has to be added into each build.gradle.kts file

[Sourabh Rawat]

I am using multiplatform project and I have only one root build.gradle.kts with

plugins {
  kotlin("multiplatform") version "1.4.10"
  id("com.github.johnrengelman.shadow") version "5.2.0"
  application
  kotlin("plugin.serialization") version "1.4.10"
  id("com.adarshr.test-logger") version "2.1.1"
}

I’m looking for unrar 😉

@Sourabh Rawat ktor+kotlinx.serialization doesn’t work with generic classes.

[Sourabh Rawat]

Alexey, so why does Json.encodeToString works fine for the same. Also, how would I implement my use case of ApiResponse. Do I have to implement a custom serializer?

[Sourabh Rawat]

What I am saying is Json.encodeToString(ApiResponse(..)) works fine.

[aleksey.tomin]

Yes. It’s not a kotlinx.serialization problem. It’s a problem with ktor + kotlinx.serialization
Will you create a bugreport in ktor with you code?

[Sourabh Rawat]

Sure. Thanks

I've created an issue about this problem.
