Hi Team ,
I just migrated to ktor 3.1.3 from 2.3.12
but not sure why call.receive is not working like its not converting my json into data class .
This is the extension function i was using earlier but now its not working .

suspend inline fun <reified T : Any> PipelineContext<*, ApplicationCall>.getBodyContent(): T {
    return call.receive()
}

i cant access it inside post block.
Can anyone help

Not working could mean everything but nothing. What’s your exact error?

MB
this is the error i get No Default Transformations found for class io.ktor.utils.io.ByteChannel and expected type TypeInfo(com.data.request.UserRequest) for call /v1/user/register

Did you setup content negotiation?

[Mohammad Zaki]

yes

fun Application.configureSerialization() {
    install(ContentNegotiation) {
        gson {}
        json()
    }
}

I figured out something its not related to deserialization its something with koin

What is the Koin version you are using? I think you need 4.1.0
