hi, I have encounter a problem when trying to decode from string. below is the simple code snippet.

fun tryDecode(someKClass: KClass<*>, jsonString: String) {
    ...
    // throw JsonDecodingException
    val result = json.decodeFromString(someKClass.serializer(), jsonString)
    ...
}

someKClass in the actual scenario is retrieved from Ktor's TypeInfo.type. This works on most cases but got stuck when the type is something like Map or List. It throws JsonDecodingException (Polymorphic serializer was not found for missing class discriminator ('null')).

is there any way to solve this or the only thing I can do is check whether the someKClass is List or Map and pass the appropriate Serializer such as ListSerializer or MapSerializer? my goal is trying to make it as generic as possible so I want to avoid any type checking as much as possible.
