Is this a proper way to get the camera manager script I created?

Development Programming & Scripting C++

void AMyProject3Character::Tick(float DeltaTime)
{
	Super::Tick(DeltaTime);
	//UE_LOG(LogTemp, Warning, TEXT("The float value is: %f"), JumpHeightUpper);
	APlayerController* PlayerController = GetWorld()->GetFirstPlayerController();
	if (PlayerController)
	{
		APlayerCameraManager* PlayerCameraManager = PlayerController->PlayerCameraManager;
		if (PlayerCameraManager)
		{
			AMainPlayerCameraManager* GetMainPlayerCamera = Cast<AMainPlayerCameraManager>(PlayerCameraManager);
			//AMainPlayerCameraManager* CameraManager = Cast<AMainPlayerCameraManager>(UGameplayStatics::GetPlayerCameraManager(GetWorld(), 0));
			if (GetMainPlayerCamera)
			{
				CameraManager->StartFOVInterpolation(CameraManager->CurrentFOVGetter() + WallRunFOVIncreaser + SpeedFOVIncreaser);
			}
			else
			{
				UE_LOG(LogTemplateCharacter, Error, TEXT("No MainPlayerCameraManager found."));
			}
		}
		else
		{
			UE_LOG(LogTemplateCharacter, Error, TEXT("No PlayerCameraManager found."));
		}
	}
	else
	{
		UE_LOG(LogTemplateCharacter, Error, TEXT("No PlayerControloler found."));
	}

“No MainPlayerCameraManager found.” is being triggered. Why could this not be working? The proper include is there. Let me know if you need any further info!

Did you specify custom camera manager class in your PlayerController class?

AMyPlayerController::AMyPlayerController()
{
	PlayerCameraManagerClass = AMainPlayerCameraManager::StaticClass();
}

Thank you for your reply! Over at reddit everyone was so mean to me : ( . I managed to make it work, but it looked a bit strange so I took it out. I made it both in blueprint and in c++.
