LUA - `FWeakObjectPtr` setter / pass struct as Out parameter?

Code Vein 2 UE5.4

Having some issues trying to call this game function:

void SetupInteractionInfo(FInteraction& OutInteraction, class AActor* InActor, class UInteractionComponent* InInteractionComponent, class UPrimitiveComponent* InOverlappedComponent);

Ideally I'd like the OutInteraction of this to be another objects playerInteractionComp.ReplicatedFocusedInteraction, but if I try passing that as the param directly, LUA gives an error about that not being a table:
Tried storing reference to a Lua table for an 'Out' parameter when calling a UFunction but no table was on the stack

If I do try using a LUA table and then copy it over onto playerInteractionComp.ReplicatedFocusedInteraction, I get a different error
[push_weakobjectproperty] Operation::Set is not supported

The FInteraction struct does have a FWeakObjectPtr inside it, in the docs there's only a get() method mentioned for that but no setter, guess that's where this error comes from (if I try setting the FWeakObjectPtr directly the same log error also appears)

Wondering if there's any other way to handle this, or if FWeakObjectPtr could have a setter added (though I'd guess there might be a reason it hasn't already..)

Show your code.

It does look like FWeakObjectPtr is very loosely supported.
Only non-param Get operations are supported, and no Set operations at all are supported.

Not sure if there was a technical reason we didn't allow this in the past, but because of recent changes we should have the ability to fully support weak pointer UE types now. I planned on working on that soon, not sure if the Lua would have to wait on it or not

Code for the table copy is

  local playerInteractionComp = actor.InteractionComponent
  local pickupInteractionComp = pickupActor.InteractionComponent
                
  local triggerComp = nil
  if pickupActor.Trigger and pickupActor.Trigger:IsValid() then
    triggerComp = pickupActor.Trigger
  end
     
  print("BeforeSetup")
  
  local interaction = {}
  pickupActor:SetupInteractionInfo(interaction, actor, pickupInteractionComp, triggerComp)
  
  print("AfterSetup")
  
  playerInteractionComp.ReplicatedFocusedInteraction = interaction
  
  print("AfterCopy")
  -- test setting the weak ptrs directly
  playerInteractionComp.ReplicatedFocusedInteraction.Sender = interaction.Sender:get()
  playerInteractionComp.ReplicatedFocusedInteraction.Receiver = interaction.Receiver:get()
  
  print("AfterAssign")

With that the log shows

BeforeSetup
AfterSetup
[push_weakobjectproperty] Operation::Set is not supported
[push_weakobjectproperty] Operation::Set is not supported
AfterCopy
[push_weakobjectproperty] Operation::Set is not supported
[push_weakobjectproperty] Operation::Set is not supported
AfterAssign

afaik two of them appear before AfterCopy since FInteraction has two WeakObjectPtr inside:

struct FInteraction
{
	FInteractionPriority PriorityData;	// 0x0000 (size: 0x4)
	FInteractionUIInfo UIInfo;	// 0x0008 (size: 0x20)
	TWeakObjectPtr<class UInteractionComponent> Sender;	 // 0x0028 (size: 0x8)
	TWeakObjectPtr<class AActor> Receiver;	// 0x0030 (size: 0x8)
	FGameplayTagRequirements GameplayTagRequirements_OnExecute;	 // 0x0038 (size: 0x88)

}; // Size: 0xC0
