I'm trying to create an inventory system and an object I'm getting in code is reading as Nil.
this is the related code

const slot_class = preload("res://misc/objects/item.gd")
onready var inventory_slots = $ColorRect/GridContainer

func _ready():
	for slot in inventory_slots.get_children():
		slot.connect("gui_input", self, "slot_gui_input", [slot])

func slot_gui_input(event: InputEvent, slot: slot_class):
	if event is InputEventMouseButton:
		if event.button_index == BUTTON_LEFT && event.pressed:
			if slot.item:
				holding_item = slot.instance().item
				slot.pick_from_slot()
				holding_item.global_position = get_global_mouse_position()

Which object is nil?

DaveTheCoder slot in slot_gui_event

I suggest setting a breakpoint at the line that causes the error, and when the breakpoint hits, use the Remote tab in the Scene dock to examine the active scene tree to verify that all the inventory slots nodes are still there.

I figured out what was wrong.
I used the wrong script for the slot class...😐
