Adding annotations to the type parameter of

HttpClient.get<T>()

causes compilation to fail with

Annotated types are not supported in typeOf

http.get<BaseResponse<@Serializable(with = ItemSerializer::class) Item>>("/v1/items/$id")

Failed to find anything related on google/youtrack/github . Filed a YT-issue here, but would be happy to close if someone can help me figure out what I’m doing wrong, or why this shouldn’t work, in general..

You can just annotate the definition of the

Item

class.

Tried that.. broke something else 😅

org.jetbrains.kotlin.backend.common.BackendException: Backend Internal error: Exception during IR lowering

I suggest creating an issue for the

BackendException

here.

Thanks @Aleksei Tirman [JB], I’ll try to make a small repro and post there.
