Compiling Kotlin to JS failes: TranslationRuntimeException

JavaScript
1

Hello,

I’ve got a problem with the kotlin js compiler.

When I try to compile my code, I get the following exception:

org.jetbrains.kotlin.js.facade.exceptions.TranslationRuntimeException: Unexpected error occurred compiling the following fragment: 'BackgroundMessageService.onReceive(::onTrans
lationRequest)' at (113,5) in .../HoverTranslateWebExtension/background_script/src/main/kotlin/background_script.kt

It worked fine until I changed the following interface:

I only added “suspend” to make it work with callbacks which are co-routines.

And this is the place where the compiler fails:

Is this a bug, or did I do something wrong. Intellij seems fine with the code

I just played around with it, and found a way how get the compiler to compile the code:

Is this a compiler bug? If so I will create a bug report here:
https://youtrack.jetbrains.com

So I just ended up wrapping the code within another lambda and then call it. So I guess the wrapping lambda will become a suspend function implicitly. In this scenario I had to be more explicit regarding the types of the lambda.

Here is another version which compiles, but with less explicit typing:

It’s probably another duplicate of https://youtrack.jetbrains.com/issue/KT-27855

@rjaros I think you are right. It looks like the same issue. And the ticket you have posted already has 2 other duplicates linked.

Awesome, and I just created the next duplicate.

Just add a comment to your new issue that it might be a duplicate, but you only found out after you created it. That way the kotlin team does not need to spend too much time figuring out that it’s a duplicate.
