When the @Head request,the KotlinExtensions will always throw KotlinNullPointerException


i found the method which not check the body is null,but it need the continuationBodyNullable in HttpServiceMethod be true,and i never found which place can change it to true,it always be false.
i change it like this ,and it be ok.
import retrofit2.Response
...
@HEAD
suspend fun checkHDVideo(@Url url:String): Response<Void>
but the continuationBodyNullable in HttpServiceMethod always be false still has not solution. is that a property which for furture?
is there any way we can pass param continuationBodyNullable into HttpServiceMethod ?
Is it going to be fixed? It's disappointing that handling 204 response code requires extra effort and an ugly Response<Unit> return type.
