viewport Y NaN (2D)

Question

I’m new to Godot Engine, and I’m trying to learn by making a simple Space Invaders-style game. I’m having a problem with the viewport. When I log the viewport, the X value is correct, but the Y value is NaN. Here’s the code I have so far. I’ve included a screenshot of my settings.

My code :
using Godot;
using System.Collections.Generic;
using System.Linq;
using System;

public partial class ScrollingBackground : Node2D
{
[Export]
public float Speed = 100f;

[Export]
public Camera2D MainCamera;

[Export]
public bool isRandom = false;

private List<Sprite2D> parts;
private Vector2 viewportSize;
private RandomNumberGenerator rng = new RandomNumberGenerator();

public override void _Ready()
{
	viewportSize = GetViewportRect().Size;
	GD.Print($"Viewport size: {viewportSize}");
}

The result of GD.Print : Viewport size: (1920, NaN)

I searched but couldn’t find this issue on this forum or any other, and I also asked the AI, which didn’t find anything either…
Thank you in advance for your help

If you turn off the embedded play and run the game again, do you still see NaN?
I had similar issues before, and disabling embedded window eliminated these issues completely. Give it a go.

Make sure that’s turned off and try again.

Hi ! Thank you very much ! Now it’s working

The irony is that right before working on the feature where I needed the viewport, I actually looked into how to put my run window in the same window because I was sick of switching back and forth between them
