Hello
in the context of kotlin/js
Switching to k2 compiler brings up the following error:

[NON_EXPORTABLE_TYPE] Exported declaration uses non-exportable return type 'kotlin. js. Promise<*>'.

for the following code:

fun foo(): Promise<*> = ...

When with the non k2 compiler, this doesn’t happen

With the non k2 compiler, Promise<Unit> isn’t exportable, which is why i’m using Promise<*>
Interestingly though, this isn’t always the case, and sometimes i don’t get a warning for Promise<Unit> , when the return type is inferred and not explicit. I can’t prove it now, but i’ve seen this happen

So I cannot use the k2 mode right now it seems

in any case, I’m curious as to why Promise<Unit> isn’t exportable

Hello! Thank you for the report, I can confirm there's an inconsistency in which types are considered exportable, both between K1 and K2 and between K1 and the documentation for @JsExport. Filed: KT-74389
