Can't get a pawn to overlap a sphere

Hello,

I am trying to have a simple sphere colliding with my Character.
My Character as Collision Preset PAWN and my Sphere the following code :

Weapon.h

	UFUNCTION()
	virtual void OnSphereEndOverlap(
		UPrimitiveComponent* OverlappedComponent,
		AActor* OtherActor,
		UPrimitiveComponent* OtherComp,
		int32 OtherBodyIndex
	);

Weapon.cpp

#include "Components/SphereComponent.h"
#include "Components/WidgetComponent.h"
#include "Vakamai/Character/PlayerCharacter.h"

AWeapon::AWeapon()
{
	PrimaryActorTick.bCanEverTick = false;
	bReplicates = true;

	WeaponMesh = CreateDefaultSubobject<USkeletalMeshComponent>(TEXT("WeaponMesh"));
	WeaponMesh->SetCollisionResponseToAllChannels(ECollisionResponse::ECR_Block);
	WeaponMesh->SetCollisionResponseToChannel(ECollisionChannel::ECC_Pawn, ECollisionResponse::ECR_Ignore);
	WeaponMesh->SetCollisionEnabled(ECollisionEnabled::NoCollision);
	WeaponMesh->SetupAttachment(RootComponent);
	SetRootComponent(WeaponMesh);

	InteractionSphere = CreateDefaultSubobject<USphereComponent>(TEXT("InteractionSphere"));
	InteractionSphere->SetCollisionResponseToAllChannels(ECollisionResponse::ECR_Ignore);
	InteractionSphere->SetCollisionEnabled(ECollisionEnabled::NoCollision);
	InteractionSphere->SetupAttachment(RootComponent);
}

void AWeapon::BeginPlay()
{
	Super::BeginPlay();
	
	if (HasAuthority())
	{
		if (GEngine)
			GEngine->AddOnScreenDebugMessage(-1, 15.0f, FColor::Yellow, TEXT("Authority"));
		InteractionSphere->SetCollisionEnabled(ECollisionEnabled::QueryAndPhysics);
		InteractionSphere->SetCollisionResponseToChannel(ECollisionChannel::ECC_Pawn, ECollisionResponse::ECR_Overlap);
		InteractionSphere->OnComponentBeginOverlap.AddDynamic(this, &AWeapon::OnSphereBeginOverlap);
		//InteractionSphere->OnComponentEndOverlap.AddDynamic(this, &AWeapon::OnSphereEndOverlap);
	}

	if (PickupWidget)
	{
		PickupWidget->SetVisibility(false);
	}
}

void AWeapon::OnSphereBeginOverlap(UPrimitiveComponent* OverlappedComponent, AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult& SweepResult)
{
	if (GEngine)
		GEngine->AddOnScreenDebugMessage(-1, 15.0f, FColor::Yellow, TEXT("OnSphereBeginOverlap"));
	APlayerCharacter* PlayerCharacter = Cast<APlayerCharacter>(OtherActor);
	if (PlayerCharacter && PickupWidget)
	{
		PickupWidget->SetVisibility(true);
	}
}

void AWeapon::Tick(float DeltaTime)
{
	Super::Tick(DeltaTime);

}

I Enter the Authority, so the event and all should be set, but I never get to see my OnSphereBeginOverlap.

Both my Character and Sphere are set to “Generate Overlap Event”. My Sphere trigger is large, and when I tried to use blueprint event “OnActorBeginOverlap” it triggered, but not the callback in my code.

What I am missing ?
