This works in Godot version 3.2, but in version 4.0.3 I get an error with get_used_cells()
extends Node2D
var map = TileMap
func _ready():
map = get_node(“TileMaps/TileMap”)
configure_camera()
func configure_camera():
get_node(“Player/Camera2D”).limit_left = map.get_used_cells()[-1].x * map.cell_size.x
get_node(“Player/Camera2D”).limit_right = map.get_used_cells()[map.get_used_cells().size() - 1].x * map.cell_size.x
Can you copy and paste the error from the Godot debugger, then edit your answer and add it in? That’d help us help you track it down 
From a quick glance though, the second line, var map = TileMap doesn’t look valid, but hard to say without an error.

Yep. @Tom Mertz is correct (the error is in the image - though hard to read). Your map variable is null…

Ah, based on your scene tree post, you have a character case error in your get_node() call. Notice your node is named Tilemaps, but the get_node() call is referencing TileMaps.

I can’t see the images, I just see a 
symbol. But I trust @jgodfrey

Huh… Weird. I can see the images on my laptop, but not on my phone…
¯\_(ツ)_/¯

As documented, get_used_cells() requires a layer argument in Godot 4.x.
