Invalid get index ''Item' (on base: 'String'). (conflicts with null to my mind)

Code:
func _ready():
for i in PlayerData.inv_data.keys():
var inv_slot = $InventoryBack.get_node(i)
print(PlayerData.inv_data)
if PlayerData.inv_data[str(i)][“Item”] != null: //error line
var item_name = GameData.item_data[str(PlayerData.inv_data[i][“Item”])][“ItemName”]
var icon_texture = load(“res://Assets/Items/ID” + str(PlayerData.inv_data[i][“Item”]) + “.png”)
inv_slot.get_node(“Icon”).set_texture(icon_texture)

Console:
//{ “Inv1”: { “Item”: “1” }, “Inv2”: { “Item”: }, “Inv3”: “0”, “Inv4”: “3”, “Inv5”: { “Item”: }, “Inv6”: { “Item”: }, “Inv7”: { “Item”: }, “Inv8”: { “Item”: } }

JSON:
{“Inv1”:{“Item”:“1”},“Inv2”:{“Item”:null},“Inv3”:“0”,“Inv4”:“3”,“Inv5”:{“Item”:null},“Inv6”:{“Item”:null},“Inv7”:{“Item”:null},“Inv8”:{“Item”:null}}

Question

Invalid get index '‘Item’ (on base: ‘String’).

Dont undertstand the error. Tried to fix with stringify, but it didnt help a lot.

in which line there is this error ?
this could be your Player.inv_data[index] value is a String type, instead of what you wanted it to be a Dictionary type

I edited

[zdrmlpzdrmlp]

yes, so try add this before the error line

print(PlayerData.inv_data)

this should confirm whether or not your inv_data dictionary’s value is String type or Dictionary type

[Terraxin0_0]

Wrote it. It repeats three times btw, so logic (for loop) is passing.

@Terraxin0_0

“Inv3”: “0”, “

this what made the error
in inv3’s value there is no Dictionary key of Item

show how you organize the inv_data of the player

[Terraxin0_0]

Ah, I see the problem

[zdrmlpzdrmlp]

yes, your issue is there are these inv values that has Dictionary with Item as key, some just pure string of “0”
the way you organize the inventory’s inv data may be wrong

[zdrmlpzdrmlp]

if you intend to keep the pure string of “0” for inv3, then the condition for checking will need to change

This problem is created by my resaving function…
Im saving badly json file

[Terraxin0_0]

TY so much! I fixed saving process and all worked!

PlayerData.inv_data[target_inv_slot] = data[“origin_item_id”] → PlayerData.inv_data[target_inv_slot][“Item”] = data[“origin_item_id”]
