After update to ktor 1.4.0, the KotlinxSerializer is missing. Is there a way to solve this?

[e5l]

Hey, could you tell me what dependency are you using?

[wellingtoncosta]

// common
implementation("io.ktor:ktor-client-core:1.4.0")
implementation("io.ktor:ktor-client-json:1.4.0")
implementation("io.ktor:ktor-client-logging:1.4.0")
implementation("io.ktor:ktor-client-serialization:1.4.0")

// android
implementation("io.ktor:ktor-client-android:1.4.0")
implementation("io.ktor:ktor-client-serialization-jvm:1.4.0")

// ios
implementation("io.ktor:ktor-client-ios:1.4.0")
implementation("io.ktor:ktor-client-serialization-native:1.4.0")

[wellingtoncosta]

Before it was:

// common
implementation("io.ktor:ktor-client-core:1.3.2")
implementation("io.ktor:ktor-client-json:1.3.2")
implementation("io.ktor:ktor-client-logging:1.3.2")
implementation("io.ktor:ktor-client-serialization:1.3.2")

// android
implementation("io.ktor:ktor-client-android:1.3.2")
implementation("io.ktor:ktor-client-core-jvm:1.3.2")
implementation("io.ktor:ktor-client-logging-jvm:1.3.2")
implementation("io.ktor:ktor-client-serialization-jvm:1.3.2")

// ios
implementation("io.ktor:ktor-client-ios:1.3.2")
implementation("io.ktor:ktor-client-core-native:1.3.2")
implementation("io.ktor:ktor-client-logging-native:1.3.2")
implementation("io.ktor:ktor-client-serialization-native:1.3.2")

Consider using

io.ktor:ktor-client-serialization

in common and remove platform dependencies

[wellingtoncosta]

@e5l I removed the platform dependencies, but the KotlinxSerializer is still missing.

Could you share small reproducer? I'm going to check the problem

[wellingtoncosta]

What do you mean by “small reproducer”?

[e5l]

I mean the project with configuration and code-snippet

[e5l]

Cause I can't reproduce it locally

[wellingtoncosta]

Ok. I have the following configuration:

private val json = Json {
    ignoreUnknownKeys = true
    useArrayPolymorphism = true
    isLenient = true
}

private val instance = HttpClient {
    configureJson()
    configureLogging()
    configureDefaultRequest()
    configureResponseValidation()
}

private fun HttpClientConfig<*>.configureJson() {
    install(JsonFeature) {
        serializer = KotlinxSerializer(json)
    }
}

And the current dependencies are:

// common
implementation("io.ktor:ktor-client-core:1.4.0")
implementation("io.ktor:ktor-client-json:1.4.0")
implementation("io.ktor:ktor-client-logging:1.4.0")
implementation("io.ktor:ktor-client-serialization:1.4.0")

// android
implementation("io.ktor:ktor-client-android:1.4.0")

// ios
implementation("io.ktor:ktor-client-ios:1.4.0")

[wellingtoncosta]

@e5l any idea?

[wellingtoncosta]

It’s so stranger cause the KotlinxSerializer is in the source code.

[manlan]

This happens for me too.
Can't use it with Ktor server.

Maybe io.ktor:ktor-client-serialization could be updated in the documentation here? https://ktor.io/docs/json-feature.html
It still says that I need to used the native version. That got me a bit confused until I looked up this thread.
