I am following a tutorial about grid based movement, and I am currently facing an error of my arugment can’t be converted from Vector2 to string when my argument is a Vector2 and my function asks for Vector2.

The reference can be found in https://www.youtube.com/watch?v=4JaHSLA2CKs at 8:01

for (int x = 0; x< gridSize.x; x++){
            for(int y = 0; y < gridSize.y; y++){
                Vector2 cords = new Vector2Int(x,y);
                grid.Add(cords, new Node(cords));
}
}

I expected the function to take the arugment becasue they are both Vector2
