Hello,

I have a Kotlin/JS project only (not multiplatform) where I import the library like this:

plugins {
    kotlin("js") version "1.5.10"
}

repositories {
    mavenCentral()
}

kotlin {
    js(IR) {
        binaries.executable()
        browser()
    }

    sourceSets {
        val main by getting {
            dependencies {
                implementation("org.jetbrains.kotlinx:kotlinx-datetime:0.3.1")
            }
        }
    }
}

But when I try to compile, I get this error

> Task :compileKotlinJs FAILED
e: java.lang.AssertionError: Built-in class kotlin.Unit is not found

How should I import this?

Thanks for your help.

It works if I remove IR

Maybe try bumping Kotlin version to 1.5.3x or 1.6.0. Right now the app is being built with an older Kotlin version than the library is, which isn't always compatible.

Yes, it works. Sorry for the noise…
