After upgrading to Kotlin 2.2.20-Beta2 some of my tests no longer work with a strange webpack error. See 🧵

Hi! Hopefully this should be fixed in 2.2.20-RC, which is just around the corner. Could you please try running your tests with 2.2.20-RC-230?

[Robert Jaros]

I need KSP for my project so I don't know if it's possible.

[broadway_lamb]

Should be possible, you can try to ignore the warning about KSP version mismatch and see if it works.

[Robert Jaros]

Will try that. Thanks.

[broadway_lamb]

If it doesn't work for you, you can try cleaning the Gradle cache (rm -rf ~/.gradle).

[Robert Jaros]

What maven repo should I add to use dev kotlin version?

[broadway_lamb]

<https://redirector.kotlinlang.org/maven/dev/>

Correction: the version should be 2.2.20-RC-233.

[Robert Jaros]

Unfortunately it still doesn't work. The same error with RC-233. It only fails with wasmJsBrowserTest so I should probably post this to #CDFP59223 channel.

[broadway_lamb]

Thanks for trying out the RC! Seems like this story is not over yet…

I should probably post this to #CDFP59223

It doesn't matter really: both Kotlin/JS and Kotlin/Wasm use the same set of NPM dependencies, with the same versions.

I'd appreciate if you could create a ticket though: kotl.in/issue. Even better if you could attach your project.

[Robert Jaros]

Js browser tests are not working as well, so I've changed the title of the issue.

[broadway_lamb]

Thank you!
