Plese help me guys! BCE0019: 'GetComponent' is not a member of 'Object'.

I'm developing a map for pathfinding AI in my mobile game, and i'm really getting confused to fix this error: " Assets/Scripts/AIpathDoorScript.js(40,69): BCE0019: 'GetComponent' is not a member of 'Object'. " it works fine in PC, Mac & Linux development build but i keep on getting errors when i'm running it in an android development build. can someone pls help me, i've tried everything but i can't really fix it. here's the code:

AIpathDoorScript:

     var cells = new Array();
     var doorsToCells = new Array();
     var imediateCells = new Array();
     var testForCells : boolean = true;
     var waitToTestCells : float = 2;
     var stage : int = 1;
      
     @HideInInspector
     var doorOpen : boolean = true;
      
     function Awake ()
     {
         doorOpen = true;
         cells = GameObject.FindGameObjectsWithTag("AIpathCell");
         doorsToCells.length = cells.length;
         testForCells = true;
         waitToTestCells = 2;
         stage = 1;
     }
      
     function Update ()
     {
         if (testForCells && waitToTestCells <= 0)
         {
             for (var imediateCell : GameObject in imediateCells)
             {
                 for (var i : int = 0; i <= cells.length - 1; i++)
                 {
                     if (cells[i] == imediateCell)
                         doorsToCells[i] = 1;
                 }
             }   
            
             for (stage = 2; stage <= cells.length; stage++)
             {
                 for (i = 0; i <= cells.length - 1; i++)
                 {
                     if (doorsToCells[i] == stage - 1)
                    
                         for (var checkDoor : GameObject in cells[i].GetComponent(AIpathCellScript).doors)
                         {
                             if (checkDoor != gameObject)
                             
                             {
                                 for (var checkCell : GameObject in checkDoor.GetComponent(AIpathDoorScript).imediateCells)
                                 {
                                     for (var j : int = 0; j <= cells.length - 1; j++)
                                     {
                                         if (cells[j] == checkCell && doorsToCells[j] == null)
                                             doorsToCells[j] = stage;
                                     }
                                 }
                             }
                         }
                 }
             }
                
            
             testForCells = false;
         }
         waitToTestCells -= 1;
     }
      
     function OnTriggerEnter (other : Collider)
     {
         if (other.tag == "AIpathCell")
             imediateCells.Add(other.gameObject);
     }

Please help here guys.. :(
