I've got a method that fails to deserialize:

fun getAll(): Collection<User>

I get:

kotlinx.serialization.SerializationException: Can't locate argument-less serializer for class LinkedValues. For generic classes, such as lists, please provide serializer explicitly.

I think I need to somehow indicate that this method should deserialize with User.serializer().list. But I'm not sure how to do that.

I tried adding this to the method:

@Serializable(with = User.serializer().list)

But the annotation is not applicable to member functions.

Fixed - had to return a List, not a Collection.
