How to attach a Spawned GameObject.transform to CinemachineVirualCamera.Follow through script

Question

I'm trying to spawn the Player and attach the Player.transform to CinamachineVirtualCamera.Follow to make the camera follow the player. And here is my script.

using Cinemachine;
using UnityEngine;

public class GameManager : MonoBehaviour
{
    public static GameManager sharedInstance = null;
    private SpawnPoint playerSpawnPoint;
    private CinemachineVirtualCamera camFollowPlayer;
    private void Awake()
    {

        if (sharedInstance != null && sharedInstance != this)
            Destroy(gameObject);
        else sharedInstance = this;
    }
    private void Start()
    {
        playerSpawnPoint = GameObject.Find("PlayerSpawnPoint").GetComponent<SpawnPoint>();
        SetupScene();
    }
    public void SetupScene()
    {
        SpawnPlayer();
    }
    public void SpawnPlayer()
    {
        if (playerSpawnPoint != null)
        {
            GameObject player = playerSpawnPoint.SpawnObject();
            camFollowPlayer.Follow = player.transform;    //my code got error NullExceptionReference here
        }
    }
}

You can expose variables to inspector with [SerializeField] so you would need to look for them with GameObject.Find(gameObjectName).GetComponent<ClassOfObject>();

You need to add reference to the Camera and use ResolveFollow to pass player transform to it.

[SerializeField] private Cinemachine​Virtual​Camera​Base camFollowPlayer;

public void SpawnPlayer()
    {
        if (playerSpawnPoint != null)
        {
            GameObject player = playerSpawnPoint.SpawnObject();
            camFollowPlayer.ResolveFollow(player.transform); 
        }
    }
