External Editor (Language Server) - Could not find base class / Could not find type in the current scope

[michaelschufi]

Godot version

v4.1.1.stable.official [bd6af8e]

System information

Godot v4.1.1.stable - Windows 10.0.19045 - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1080 (NVIDIA; 31.0.15.3623) - Intel(R) Core(TM) i7-9700K CPU @ 3.60GHz (8 Threads)

Issue description

An external editor (in my case VS Code) cannot resolve classes. Even though it's working in the Godot Editor:

The same is happening for type annotations:

I may be just doing something wrong. But the editor can definitely connect to the language server ...

Steps to reproduce

1. Create three scripts

foo.gd

extends Node
class_name Foo

var foo_variable = "foo"

bar.gd

extends Foo
class_name Bar

func _physics_process(delta: float) -> void:
  print(self.foo_variable)

and baz.gd

class_name Baz

func my_function(foo: Foo):
  foo.foo_variable = 5

2. Open them in VS Code

(Make sure you have VS Code configured correctly, as per the README.md of the Godot VS Code extension.)

Open the bar.gd and baz.gd and hover over the errors.

Same issue here using VScode and Godot 4.1.
I discovered the issue when creating @export vars in the parent class and then trying to use them in a child class.
VScode shows the errors, but the game runs without problem and the variables are available.

This is a real PITA.
While looking for solutions, found the following issues in https://github.com/godotengine/godot-vscode-plugin and they seem to point to a LSP bug:

• Could not find type in the current scope. godot-vscode-plugin#487
• Global Variables are not properly detected godot-vscode-plugin#431
• 'The identifier X isn't declared in the current scope' in inherited classes godot-vscode-plugin#266

Issues form this repo that seem related:

• [3.x] Editor says variable isn't declared in current scope but is able to use it at runtime. #68711
• External Editor: Can't access parent class variables in child class but can access them after restarting Godot #39713

The MRP isn't available anymore and I can't find a cached version, but creating a new project with just those three scripts, I can't reproduce the issue in v4.4.dev.custom_build [92e51fc]
