Hi, I'm migrating from Kodein to Koin in Compose Multiplatform project with Wasm support
Today I stuck with this error

when tried to add Koin to Ktor server

private fun connectServer() = embeddedServer(
    factory = Netty,
    port = 8080,
    module = { setApplicationModule() } // configureKoin here
).start(wait = true)

internal fun Application.configureKoin() {
    install(Koin) {                    // <--- Error here
        slf4jLogger(level = Level.DEBUG)
        modules(serverModules)
    }
}

I use these versions

koin = "3.6.0-wasm-alpha2"
ktor = "3.0.0-wasm2"
ktor-plugin = "3.0.0-beta-1"

koin = { module = "io.insert-koin:koin-core", version.ref = "koin" }
koin-ktor = { module = "io.insert-koin:koin-ktor", version.ref = "koin" }
koin-ktor-logger = { module = "io.insert-koin:koin-logger-slf4j", version.ref = "koin" }

Can you please tell me what did I wrong? Thanks

Seems to be complaining about a missing plug-in for Application monitoring or so. Where the ApplicationEnvironment is at. Or maybe this plug-in dependency is applied but not the version with that specific signature

[Andrey Larionov]

I guess it's about version incompatibility, but I can't figure out what's exactly wrong

[Andrey Larionov]

Because it worked with Kodein

[Robert Jaros]

Try using latest beta instead of alpha version.

[Andrey Larionov]

@Robert Jaros Does it work with wasm ?

[Andrey Larionov]

koin = "3.6.0-Beta4"
koin-compose = "1.2.0-Beta4"

koin = { module = "io.insert-koin:koin-core", version.ref = "koin" }
koin-ktor = { module = "io.insert-koin:koin-ktor", version.ref = "koin" }
koin-ktor-logger = { module = "io.insert-koin:koin-logger-slf4j", version.ref = "koin" }
koin-compose = { module = "io.insert-koin:koin-compose", version.ref = "koin-compose" }
koin-android = { module = "io.insert-koin:koin-androidx-compose", version.ref = "koin" }

Changed koin-compose version, but still getting an error

TL;DR - Koin doesn't support Ktor v3+ now, so I had to downgrade ktor-server deps:

ktor = "2.3.11"
ktor-plugin = "2.3.11"
