[3.6.0-Beta4] install(Koin) error - Koin can't be run

[nowiwr01w]

Describe the bug I set Koin like this:

internal fun Application.configureKoin() {
    install(Koin) {
        slf4jLogger(level = Level.DEBUG)
        modules(serverModules)
    }
}

When I run a Server, I get an error:

Exception in thread "main" java.lang.NoSuchMethodError: 'io.ktor.events.Events io.ktor.server.application.ApplicationEnvironment.getMonitor()'
    at org.koin.ktor.plugin.KoinPluginKt.setupMonitoring(KoinPlugin.kt:57)
    at org.koin.ktor.plugin.KoinPluginKt$Koin$2.invoke(KoinPlugin.kt:41)
    at org.koin.ktor.plugin.KoinPluginKt$Koin$2.invoke(KoinPlugin.kt:37)

If you go to KoinPlugin.kt at 57 like and check monitor variable type in this function:

internal fun PluginBuilder<KoinApplication>.setupMonitoring(koinApplication: KoinApplication) {
    val monitor = environment?.monitor
    monitor?.raise(KoinApplicationStarted, koinApplication)
    monitor?.subscribe(ApplicationStopping) {
        monitor.raise(KoinApplicationStopPreparing, koinApplication)
        koinApplication.koin.close()
        monitor.raise(KoinApplicationStopped, koinApplication)
    }
}

it says

val monitor: [Error type: Not found recorded type for environment?.monitor]

Koin module and version: Versions:

koin = "3.6.0-Beta4"
ktor = "3.0.0-wasm2"
ktor-plugin = "3.0.0-beta-1"
logback = "1.5.3"

Libraries:

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

ktor = { id = "io.ktor.plugin", version.ref = "ktor-plugin" }
ktor-server-core = { module = "io.ktor:ktor-server-core", version.ref = "ktor" }
ktor-server-netty = { module = "io.ktor:ktor-server-netty", version.ref = "ktor" }

logback = { module = "ch.qos.logback:logback-classic", version.ref = "logback" }

Code example:

 plugins {

[nowiwr01w]

Also fails with 3.6.0-Beta3, 3.6.0-Beta2, 3.6.0-alpha3, 3.6.0-wasm-alpha2, 3.6.0-wasm-alpha1

[nowiwr01w]

Found out it fails with any Koin version, so I guess it's because Koin doesn't support Ktor 3+ now

When I changed to

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

it fixed

@arnaudgiuliani If it's possible can you please provide in release notes what max version of Ktor is supported by Koin?
