Is it possible to use kotlinx.serialization with the newest version of ktor server? It seems like the documentation is outdated, since I can't find the serialization() function in kotlinx.serialization.

https://ktor.io/docs/serialization-converter.html#configuration

install(ContentNegotiation) {
        json(Json {
            ignoreUnknownKeys = true
            isLenient = true
            prettyPrint = true
        })
    }

[Joost Klitsie]

This is what I use with ktor 1.4.0

[Joost Klitsie]

the Json is from the serialization

[Patrick]

It says: required: JsonObjectBuilder.() -> Unit, Found: Json

[Patrick]

I am using ktor 1.4.0 and kotlinx.serialization version 1.0.0-RC2

[Joost Klitsie]

Maybe try serialization 1.0.0-RC

[Joost Klitsie]

OR ktor 1.4.10 with serialization 1.0.0-RC2

[Patrick]

is that the version you are using?

[Joost Klitsie]

yes

[Patrick]

ok i'll try 1.4.10

[Joost Klitsie]

I use 1.4.0 with 1.0.0-RC

[Joost Klitsie]

I think for 1.4.10 you can use 1.0.0-RC2

[Joost Klitsie]

but you also have to add "kotlinx-serialization-json"

[Joost Klitsie]

org.jetbrains.kotlinx:kotlinx-serialization-json:1.0.0-RC2

[Patrick]

I don't think version 1.4.10 exists

[Joost Klitsie]

sorry 1.4.1

[Patrick]

Ah I see

[Patrick]

I think it works with 1.4.1

[Joost Klitsie]

which supports kotlin 1.4.10 😄

[Patrick]

Hmm I am still getting the same error

[Joost Klitsie]

which ktor dependencies do you have?

[Patrick]

val ktorVersion = "1.4.1"

implementation("io.ktor:ktor-server-core:$ktorVersion")
    implementation("io.ktor:ktor-server-netty:$ktorVersion")
    implementation("org.jetbrains.kotlinx:kotlinx-serialization-json:1.0.0-RC2")

[Joost Klitsie]

do you also include io.ktor:ktor-serialization:1.4.1

[Patrick]

I didn't, it looks better now

[Patrick]

But now I am getting this error: Exception in thread "Thread-0" java.lang.NoSuchMethodError: 'kotlinx.serialization.json.Json kotlinx.serialization.json.JsonKt.Json$default(kotlinx.serialization.json.Json, kotlin.jvm.functions.Function1, int, java.lang.Object)'

[Patrick]

At least it compiles now
