Hi how can i change source image of Image?

My code here. But gets nullreferenceexception

    Image image;
    public Sprite newImage;
    private void Start()
    {
        image = GetComponent<Image>();
    }
    public void ChangeBackgroundMaterial()
    {
        image.sprite = newImage;

    }

1. Find out what is null
2. Find out why it’s null
3. Fix it

3 simple steps.

My guess, image is null.
