Exit by pressing

[Mikhail666999]

Hello it's me again) This time I have a different problem. I'm trying to exit by clicking.
I tried to do so
self:get_tree().quit();

godot throws this error
E 0:00:02.480 quit: attempt to index local 'o' (a nil value) stack traceback: [string "res://assets/player/player.lua"]:17: in function <[string "res://assets/player/player.lua"]:11> in call _physics_process @ res://assets/player/player.lua <C source code++>lps_init_script:1344 @ quit()

What am I wrong about?

The problem is probably the lack of using Lua's method notation:

self:get_tree():quit()
            -- ^ here!

Please don't. Using a new language is always tricky, and it gets worse if the error messages are cryptic suchs as the one you got there.
