Assign ScriptableObject (Inventory DataBase)

hi i am creating inventory for my game and i got stuck when script need to choose which scriptableObject (DataBase) to use for a different weapon. i want script to look what weapon is active then assign database of that weapon to the script and let script do its magic. I tried setting what dataBase to use with a Resource.load

 for (int i = 0; i < Aim.transform.childCount; i++)
         {
             if (Aim.transform.GetChild(i).gameObject.activeSelf == true)
             {
                 scriptableObject = Resources.Load<ItemWeapon>(Aim.transform.GetChild(i).name);
                 
                 if (delayActive != true)
                 {
                     canAttack = true;
                 }
                 break;
             }
             else
             {
                 canAttack = false;
             }
         }

i tried cloning the scriptableObject i need with the instatiate and worked to some degree (half of the code didnt work but it could instatiate bullet with force i set but bullet was created at wrong location, that was only thing that worked)

scriptableObject:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
  
  [CreateAssetMenu(fileName = "New Weapon", menuName = "Weapon")]
 public class ItemWeapon : ScriptableObject
 {
 
     [Header("Basic Data")]
     public float id;
     public new string name;
     [Multiline]public string description;
     public Sprite icon;
 
     [Header("Weapon oriented data")]
     [Range(0, 100f)]public float damage;
     public GameObject weapon;
 
     [Header("Gun")]
     public bool hasBullet;
     public bool holdToShot;
     public GameObject Bullet;
     public GameObject BulletAim;
     [Range(1,200f)]public float bulletSpeed;
     [Range(0.1f,10)]public float DestroyAfter;
     [Range(0,2f)]public float speedOfShooting;
 
     [Header("Sword")]
     public float SpeedOfAttack;
     public void Shot(Rigidbody2D RB)
     {
         RB.velocity = Bullet.transform.right * bulletSpeed;
         Destroy(Bullet, DestroyAfter);
     }
 
 }

and some example of the dataBase being used:

 void Attack()
     {
         if(canAttack == true)
         {
             scriptableObject.weapon.GetComponent<Animator>().SetBool("MouseClick", true); //activate animation
             switch (scriptableObject.hasBullet) 
             {
                 case true:
                     InstantiateBullet(scriptableObject.Bullet);//spawn bullet
                     SetInputDelay(scriptableObject.speedOfShooting); //setInputDelay (you cant shoot for some time)
                 break;
                 case false:
                     //attack with sword
                 break;
             }
         }
         else
         {
             Debuging("CanAttack is false");
         }
     }

and i always get error :

 NullReferenceException: Object reference not set to an instance of an object
 UnityEditor.Graphs.Edge.WakeUp () (at <b82d8d0a349d4d70807c2fc5746a710f>:0)

if someone have experience of creating a dataBase i would like to hear how else can i make this work or help me fix this problem

Thanks
