c++ – getting navigation path points in unreal engine

I get an Exception when executing this code:

void PaladinClass::BeginPlay(){
Super::BeginPlay();

this->PaladinAIController = Cast<AAIController>(GetController());
if(this->PaladinAIController && this->PaladinPatrolTarget)
{
    FAIMoveRequest MoveRequest;
    MoveRequest.SetGoalActor(PaladinPatrolTarget);
    MoveRequest.SetAcceptanceRadius(15.f);
    FNavPathSharedPtr NavPath;
    this->PaladinAIController->MoveTo(MoveRequest, &NavPath);
 
    TArray<FNavPathPoint>& PathPoints = NavPath->GetPathPoints();
    for(auto& Point: PathPoints)
    {
       const FVector& Location = Point.Location;
       DrawDebugSphere(GetWorld(), Location, 12.f, 12, FColor::Green, false, 10.f);
    }
  }
}

Using the debugger, I could see that the error was on

TArray<FNavPathPoint>& PathPoints = NavPath->GetPathPoints();

Where NavPath seemed to be null , but

The unreal engine crash states something like this:

Assertion failed: IsValid() [File:C:\Program Files\Epic Games\UE_5.3\Engine\Source\Runtime\Core\Public\Templates\SharedPointer.h] [Line: 1139]

I have also confirmed that I have a Navigation Mesh in the scene. Hence, I cannot seem to find the source of the issue. Any insights would be greatly appreciated.
