Hello, I’m trying to set contentType in defaultRequest but it crashesh in iOS, and when I wanna set contentType in post request,
this exception raise

I have also installed `ContentNegotation` and `json`

Fail to serialize body. Content has type: class org.metatude.paxfa.auth.login.LoginEmailRequestDto, but OutgoingContent expected.
If you expect serialized body, please check that you have installed the corresponding plugin(like `ContentNegotiation`) and set `Content-Type` header.

Could you please share a code snippet to reproduce your problem?

I just configure the HttpClient with bellow configure, and it cause a crash on iOS.

defaultRequest {
    url {
        protocol = URLProtocol.HTTPS
        host = baseUrl
    }
    contentType(ContentType.Application.Json)
   
}
 install(ContentNegotiation) {
        json()
    }

it is works on 1.6.7 but crash in 2.0.0-beta1
ps:
when you wanna send post request with data class (I also make it serialize using @Serializable it causes crash).

I cannot reproduce it with an EAP version of Ktor, like 2.0.0-eap-327 . Please try to use that version with the new native memory model enabled (kotlin.native.binary.memoryModel=experimental in Gradle). Also, include the following repositories in the Gradle build:

maven { url "<https://maven.pkg.jetbrains.space/public/p/kotlinx-html/maven>" }
maven { url "<https://maven.pkg.jetbrains.space/public/p/ktor/eap>" }
