task jsBrowserDevelopmentRun is throwing a weird webpack error. This thing was running a few runs ago

jsBrowserDevelopmentRun FAILED
[webpack-cli] Invalid configuration object. Object has been initialized using a configuration object that does not match the API schema.
 - configuration has an unknown property '_assetEmittingWrittenFiles'. These properties are valid:
   object { bonjour?, client?, compress?, dev?, firewall?, headers?, historyApiFallback?, host?, hot?, http2?, https?, liveReload?, onAfterSetupMiddleware?, onBeforeSetupMiddleware?, onListening?, open?, port?, proxy?, public?, setupExitSignals?, static?, transportMode?, watchFiles? }

Help?

Kotlin 1.5.10

Do you have custom dev-server configuration scripts?

Same problem here :

I use following versions and have no such problems:

webpack.version = "5.50.0"
webpackCli.version = "4.7.2"                webpackDevServer.version = "4.0.0-rc.0"

+1, this problem also suddenly started happening in my own independent project

[Jeff Davidson]

as a workaround, setting "kotlin.js.webpack.major.version=4" in gradle.properties is working for me, at least, but I have no dependencies on webpack 5. Kotlin 1.5.20

[Jan Weidenhaupt]

I got the same error also with Kotlin 1.5.30-RC...
@Jeff Davidson Thanks for posting the workaround! Hopefully this get fixed soon 🙂

@turansky By default the jsRun task downloads the webpack version 5.38.1 and webpack-cli version 4.7.1 in my project when using Kotlin 1.5.30-RC which i can see in the node_modules folder. Is there are way to update this versions?

@andylamax Could you, please, fill the issue in our YouTrack and attach a sample project, so we could reproduce the issue
Or is it the same problem as described here ? https://youtrack.jetbrains.com/issue/KT-48273

[Oleksandr Karpovich [JB]]

@Ilya Kalibrov [JB] it's the same problem as KT-48273

[Ilya Kalibrov [JB]]

JFYI: this issue seems obsolete for new IR BE. If you have reproduced it with IR, please, let me know

[Pitel]

@Ilya Kalibrov [JB] I'm using IR, and I have this issue since today.

Tried setting

kotlin.js.webpack.major.version=4

in gradle.properties

And now I am getting

Execution failed for task jsBrowserDevelopmentRun
> ✖ ｢wds｣: webpack Dev Server Invalid Options
  
  options should NOT have additional properties

[andylamax]

rootProject.plugins.withType(org.jetbrains.kotlin.gradle.targets.js.nodejs.NodeJsRootPlugin::class.java) {
    rootProject.the<org.jetbrains.kotlin.gradle.targets.js.nodejs.NodeJsRootExtension>().versions.webpackDevServer.version =
        "4.0.0-rc.0"
}

worked for me
