I'm generating a property in FIR that gets completed later in IR. This property is annotated with @Transient from Kotlin Serialization. It seems that something has recently changed in Kotlin Serialization — perhaps the checker has been moved to FIR — because now I'm getting the following error:

This property is marked as @Transient and therefore must have an initializing expression

I tried changing the order in which the plugins are applied, as I had a similar issue before with the AtomicFU plugin, but that workaround doesn’t work this time.

I suppose creating a fake in FIR for that property would fix the issue, but since that’s not allowed, what other workaround could I use?

You can add a null!! initializer in FIR property

[Javier]

Will try, thanks!

I have to manually create that initializer manually, or there is an utility function to get that?

[dmitriy.novozhilov]

You need to it create manually.

Is it possible to use FirStub?

atomicProperty.replaceInitializer(FirStub)

[dmitriy.novozhilov]

You can try, but I have a remembrance that it breaks fir2ir.

[Javier]

You are right:

Should not be here: class org.jetbrains.kotlin.fir.resolve.dfa.cfg.FirStub ??? class org.jetbrains.kotlin.fir.resolve.dfa.cfg.FirStub

[Javier]

This worked, thank you!

replaceInitializer(
    buildErrorExpression { diagnostic = KopyConeTemporalDiagnostic }
)

[dmitriy.novozhilov]

Probably it could be automatically added by the compiler.
Could you please create a youtrack request for that?

[Javier]

Sure 🙂
