### System information

Windows 11

### Issue description

Using the following code:

```gdscript
extends StaticBody3D

@onready var shape_3d = $CollisionShape3D

func _ready():
	var convex_shape = ConvexPolygonShape3D.new()
	var points = PackedVector3Array()
	
	points.append(Vector3(0, 0, 0))
	points.append(Vector3(1, 0, 0))
	points.append(Vector3(0, 0, 1))
	points.append(Vector3(1, 0, 1))
	
	convex_shape.points = points
	shape_3d.shape = convex_shape
```

produces the correct result:

but generates unnecessary errors:
