Object reference not set to an instance of an object.

root is an HtmlNode but when I try to access anything using SelectSingleNode or SelectNodes it will raise this error when trying to access any methods of them. 
HtmlDocument doc = new();
doc.LoadHtml($"{url}/page/{page}/");

HtmlNode root = doc.DocumentNode;
Console.WriteLine(root.GetType());
Console.WriteLine(root.SelectSingleNode("//div").GetType());
HtmlDocument doc = new();
doc.LoadHtml($"{url}/page/{page}/");

HtmlNode root = doc.DocumentNode;
Console.WriteLine(root.GetType());
Console.WriteLine(root.SelectSingleNode("//div").GetType());

Does LoadHtml actually take a URL? I would assume it takes an HTML string.

Console logging on errors isn’t a thing .net libraries do. They would throw exceptions.

Quality Python libs don’t do that either.
