Hi all. I'm running into this internal compiler error when trying to build my compose-web project.

e: java.lang.AssertionError: Assertion failed
	at org.jetbrains.kotlin.ir.backend.js.transformers.irToJs.JsAstUtilsKt.checkOnNullability(jsAstUtils.kt:451)


Execution failed for task ':app:web:compileDevelopmentExecutableKotlinJs'.
> A failure occurred while executing org.jetbrains.kotlin.compilerRunner.GradleCompilerRunnerWithWorkers$GradleKotlinCompilerWorkAction
   > Internal compiler error. See log for more details

Seems to have originated when I bumped ktor to 3.0.0-rc1 but not sure

Any clue as to what is going on?

You should report this to YT, as the compiler shouldn't fail like that.

Could you try clearing the Gradle cache and disabling KJS incremental compilation?

[xxfast]

Thanks @Edoardo Luppi whats the flag on gradle.properties to disable incremental compilation?

[Edoardo Luppi]

<http://kotlin.incremental.js.ir|kotlin.incremental.js.ir> = false

[Edoardo Luppi]

You can set these three to be sure

kotlin.incremental.js = false
<http://kotlin.incremental.js.ir|kotlin.incremental.js.ir> = false
kotlin.incremental.js.klib = false

Ok bumping to kotlin 2.0.20 seems to somehow fixed this. False alarm 🙂 Thanks anyways @Edoardo Luppi
