When building a project using Kotlin 1.3.xx, you may encounter a Gradle error if one of your dependencies (or any transitive dependency) was built using Kotlin 1.4+:

This resolution problem appears because Kotlin 1.4 introduces the choice between two different compiler backends for Kotlin/JS – a choice that was not available in Kotlin 1.3.xx.

Workaround:

In order to use the libraries, create a file called workaround_to_use_1_4_libs_in_1_3.gradle.kts in the root directory of your project, and add the following code:

    val pluginAction: Plugin<*>.() -> Unit = {
    val pluginVersion = try {
        this.javaClass.getMethod("getKotlinPluginVersion").invoke(this) as String
    } catch(e: Exception) { null }
    if (pluginVersion != null && pluginVersion.startsWith("1.3")) {
        val jsCompilerAttr = Attribute.of("org.jetbrains.kotlin.js.compiler", String::class.java)
        project.dependencies.attributesSchema.attribute(jsCompilerAttr) {
            this.disambiguationRules.add(KotlinJsCompilerDisambiguationRule::class.java)
        }
    }
}
project.plugins.withId("org.jetbrains.kotlin.multiplatform", pluginAction)
project.plugins.withId("org.jetbrains.kotlin.js", pluginAction)
// project.plugins.withId("kotlin2js", pluginAction) // maybe even `kotlin2js`
private class KotlinJsCompilerDisambiguationRule : AttributeDisambiguationRule<String> {
    override fun execute(details: MultipleCandidatesDetails<String>) {
        details.closestMatch("legacy")
    }
}

To apply the workaround, add the following snippet to your build.gradle file:

apply(from = "workaround_to_use_1_4_libs_in_1_3.gradle.kts")

i didnt find the solution I got pointed to it by some one in slack channel you track link that has the solution
