Error when declaring function with interface type as parameter

Hello, I have interface class (Interactable) which I am trying to use as a function parameter in another class (InteractionRay).

This is my Interactable.h file:

#pragma once

#include "CoreMinimal.h"
#include "UObject/Interface.h"
#include "Interactable.generated.h"

UINTERFACE(BlueprintType)
class UInteractable : public UInterface
{
	GENERATED_BODY()
};

class SPACEGAME_API IInteractable
{
	GENERATED_BODY()

public:

	UFUNCTION(BlueprintCallable, BlueprintImplementableEvent)
	UUserWidget* GetWidget();
};

And this is my InteractionRay.h file:

#pragma once

#include "CoreMinimal.h"
#include "Components/SceneComponent.h"
#include "InteractionRay.generated.h"

class IInteractable;

UCLASS( ClassGroup=(Custom), meta=(BlueprintSpawnableComponent) )
class SPACEGAME_API UInteractionRay : public USceneComponent
{
	GENERATED_BODY()

public:	
	
	UInteractionRay();

	virtual void TickComponent(float DeltaTime, ELevelTick TickType, FActorComponentTickFunction* ThisTickFunction) override;
	
protected:
	
	virtual void BeginPlay() override;

	UPROPERTY(EditDefaultsOnly)
	float RayLength;

	IInteractable* CurrentTarget = nullptr;
	
	IInteractable* GetInteractableActor();

	UFUNCTION(BlueprintImplementableEvent)
	void OnStartedLookingAt(IInteractable* Target);
};

When I try to compile I get this error:

error
error1980×156 14.3 KB

Surprisingly, when I change the parameter in OnStartedLookingAt function to some other type for example AActor*, it compiles successfully.

I tried searching for answers but without success and I’m out of ideas. I would appreciate any help.
