Hi, I'm getting

IrLinkageError: Can not read value from variable 'tmp0_safe_receiver': Variable uses unlinked class symbol 'kotlinx.coroutines.internal/LinkedListHead|null[0]'

when trying to run wasmJs with Ktor client request in a coroutine. Here is a reproducer repo: https://github.com/MichalChomo/coroutine-wasm-ir-linkage-error-reproducer
Has anyone encountered this?

Hi, I'm getting the same error. Did you resolve the issue by any chance?
To me it happens when I try to make a network request with Ktor Client(version 3.0.0-wasm2).

I was also facing the same issue. You guy's can resolve this error by upgrading the Koin to 3.6.0-wasm-alpha2 & If you are using Voyager then also upgrade that to 1.1.0-beta02. For Reference you can check my Repository: https://github.com/KhubaibKhan4/Youtube-Clone-KMP

As far as I can see Michals project doesn't use Koin, and in my project the error happens when I try to call:

val scope = rememberCoroutineScope()
val httpClient = HttpClient {}
scope.launch {
    httpClient.get("<https://jsonplaceholder.typicode.com/todos/1>")
}

This issue is all about dependencies conflict. I also faced this same issue on my 5-6 projects and I resolved this error by upgrading to latest dependencies.

[Bruno Blazinc]

Will give it a go and let you know if it worked.

[Khubaib Khan]

Sure

So, I made a clean project and started adding the various dependencies. In my case I added the following commonMain dependencies and that was causing my issues:

[versions]
jetbrains-kotlinx-bom = "1.9.0-RC"

[libraries]
jetbrains-kotlinx-bom = { group = "org.jetbrains.kotlinx", name = "kotlinx-coroutines-bom", version.ref = "jetbrains-kotlinx-bom" }
jetbrains-kotlinx-core = { group = "org.jetbrains.kotlinx", name = "kotlinx-coroutines-core" }

[Khubaib Khan]

I'll recommend to use Kotlin 2.0 with Compose Compiler. That's really amazing and enhanced alot of performance too.

[Khubaib Khan]

And Onething, Sometime Android studio didn't display the latest updates. kindly check every library latest version from GitHub or Maven Central.

Koin is not a problem here, I haven't used it at all.

I've created an issue in YouTrack: https://youtrack.jetbrains.com/issue/CMP-1588/IrLinkageError-Can-not-read-value-from-var[…]le-uses-unlinked-class-symbol-kotlinx.coroutines.internal

[jdiaz]

This is somehow related to coroutines, I literally removed that dependency and it works fine

[Michal]

Using Ktor version 3.0.0-beta-2 solves it for me.
