hey guys We have updated kotlin kotlinx and ktor in our proj kotlinlang #coroutines

hey guys! We have updated kotlin, kotlinx and ktor in our project up to versions 1.5.0 and 1.5.4. Also we decided to try new value classes in requests and responses. We deployed our changes and have faced next errors:

Untitled

Sounds like it is similar to this problem - https://kotlinlang.slack.com/archives/C1CFAFJSK/p1621019550451100

But I m not sure is it ktor issue or coroutines

if we use data class instead of value class - everything works perfectly.

The worst part of it, that we can't reproduce it on a sample project, so we face it only in our big project 🤦 But may be someone has already faced this issue and can give us any insights 🙏 In a meantime we will try to find a way how to reproduce it on a small project. Thanks!

Do you have JVM IR disabled in one of the modules?

if you are talking about

Copy code

compileKotlin {
    kotlinOptions.useIR = true
}

we didn't enable it. our config is:

Copy code

compileKotlin {
    sourceCompatibility = "$java_version"
    targetCompatibility = "$java_version"

    kotlinOptions {
        jvmTarget = "$java_version"
        allWarningsAsErrors = true
        freeCompilerArgs += "-Xopt-in=kotlin.RequiresOptIn"
    }
}

In 1.5, it's enabled by default. My question was only if you explicitly disabled it somewhere, which it seems you didn't.

AFAIK Ktor has not been released yet with a Kotlin 1.5-based version

I know it seems strange but that's what I was told (I was also bitten by it). If it's any indication, Ktor 1.5.3 depends on coroutines 1.4.3: https://ktor.io/changelog/1.5/ (and probably still Kotlin 1.4.21, but I haven't checked that)
