Can't find fix for buggy camera

I'm working on a big project and we're almost done, but when the character goes far to the left or the right the camera completely freaks out and I don't know how to fix it. The camera is supposed to follow the character smoothly but when far enough to the edges it it jitters a lot.

 using UnityEngine;
 using System.Collections;
 
 public class CameraControllerComponent : MonoBehaviour {
 
     [SerializeField]
     private PlayerComponent player;
     [SerializeField]
     private Transform gravityTracker;
 
     [SerializeField]
     private float lerpValue = 0.1f;
     [SerializeField]
     private float velocityLead = 0.1f;
     [SerializeField]
     private float slerpValue = 0.1f;
     [Range(0.1f, 2f)]
     [SerializeField]
     private float tubeNormalTracking = 1f;
 
 
 
     private void Update() {
         transform.position = Vector3.Lerp(transform.position, player.transform.position + player.rigidbody.velocity * velocityLead, lerpValue);
         //transform.position = player.transform.position;
 
         if (player.CurrentTube == null) {
             gravityTracker.rotation = Quaternion.Slerp(gravityTracker.rotation, Quaternion.LookRotation(Vector3.forward, -Physics.gravity), slerpValue);
         } else {
             gravityTracker.rotation = Quaternion.Slerp(gravityTracker.rotation, Quaternion.LookRotation(Vector3.forward, player.CurrentTube.GetNormalFromTubePosition(player.PositionOnTube / (1f/tubeNormalTracking))), slerpValue);
         }
     }
 
 }

Any and all help would be very appreciated
