I’m getting error on line 9 and also an error saying Node not found: Player/Player/Camera2D (relative to /root/World)

get_tree().current_scene points to a node, that node doesn’t have a grandchild with the path Player/Player/Camera2D, hence your camera variable gets assigned null.
When you are trying to read camera.zoom on line 9 you get an error because null type doesn’t have a zoom member.
