how to make Multimesh construction script for Godot?

Multimesh has StaticBody and CollisionBody. I have this script on my Multimesh that makes an array of objects in a row. (Fence for example)

tool  extends MultiMeshInstance    export (float) var distance:float = 1.0 setget set_distance  export (int) var count:int = 1 setget set_count  export (Mesh) var mesh:Mesh setget set_mesh  export (Vector3) var rotMesh:Vector3 setget set_rotMesh  export (Vector3) var sclMesh:Vector3 setget set_sclMesh  export (Vector3) var colMesh:Vector3  onready var coll = get_node("static/collision")    func set_distance(new_distance):      distance = new_distance      update()  func set_count(new_count):      count = new_count      update()  func set_mesh(new_mesh):      mesh = new_mesh      update()  func set_rotMesh(new_rot):      rotMesh = new_rot      update()  func set_sclMesh(new_scl):      sclMesh = new_scl      update()    func update():      self.multimesh = MultiMesh.new()      self.multimesh.transform_format = MultiMesh.TRANSFORM_3D      self.multimesh.instance_count = count      self.multimesh.visible_instance_count = count      self.multimesh.mesh = mesh      var offset = Vector3(0,0,0)      var trfMesh:Basis = Basis(rotMesh)      var extents = Vector3(colMesh.x*distance*count,colMesh.y,colMesh.z)      var shape:Shape = BoxShape.new()      shape.extents = extents      coll.Shape = shape # or coll.shape the same error      trfMesh = trfMesh.scaled(sclMesh)      for i in range(count):          self.multimesh.set_instance_transform(i, Transform(trfMesh, offset))          offset.x += distance  

I want to set CollisionShape automatically, or at least by some params through my script.

When I trying to set CollisionShape, I get:

res://scene/test.gd:40 - Invalid set index 'Shape' (on base: 'Nil') with value of type 'BoxShape'.
