C# API SDK ListFolderAsync doesn't work

Hi! 

I'm trying to list all files in a public folder which Url address I've been given, but I'm getting an error.

Here's my code, its pretty basic:

string url = "https://www.dropbox.com/sh/{ABCD}/{EFGH}?dl=0";
using (var dbx = new DropboxClient("MY TOKEN"))
{
     var sharedLink = new SharedLink(url);
     var folderContent = dbx.Files.ListFolderAsync(path: "", sharedLink: sharedLink).Result;

}

And the error says:

AdditionalInfo: System.AggregateException: One or more errors occurred. ()

I also tried to send a HTTP request via Postman, but I just get 500 Internal Server Error. Is there something wrong with this endpoint and I just need to do it some other ways?
