Hello,

I'm not able to reproduce the issue you described with the following test

[Theory]
[InlineData("https://mega.nz/file/B7BnxarD#pt_9ebHpGvzCi3LBVVfBcudIys7mZGma_wHHquWTEkE")]
public async void GetNodeFromLinkAsync_Succeeds(string fileLink)
{
  var instance = new MegaApiClient();
  await instance.LoginAnonymousAsync();
  var node = await instance.GetNodeFromLinkAsync(new Uri(fileLink));

  Assert.NotNull(node);
  Assert.Equal("fm.png", node.Name);
  Assert.Equal(597194, node. Size);
}

Could you provide a small sample?

It happens when querying a just created folder now. The created folder shows up as 'undecrypted folder' in the web file manager

using System;
using System.Collections.Generic;
using CG.Web.MegaApiClient;

namespace ConsoleApp1
{
    class Program
    {
        static INode GetRootNode(MegaApiClient client)
        {
            IEnumerable<INode> newNodes = client.GetNodes();
            INode rootNode = null;
            foreach (INode node in newNodes)
            {
                if (node.Type == NodeType.Root)
                {
                    rootNode = node;
                    break;
                }
            }
            return rootNode;
        }

        static void Main(string[] args)
        {
            MegaApiClient client = new MegaApiClient();
            try
            {
                MegaApiClient.LogonSessionToken token = client.Login("email", "pass");
                Console.WriteLine("Logged in on session {0}", token.SessionId);
                INode rootNode = GetRootNode(client);
                string upFile = args[0];
                INode testFolder = client.CreateFolder("testFolder", rootNode);
                Console.WriteLine("Created {0}, type {1}, size {2}, id {3}", testFolder.Name, testFolder.Type, testFolder.Size, testFolder.Id);
                Console.WriteLine("Getting link");
                Uri link = client.GetDownloadLink(testFolder);
                Console.WriteLine("Got link {0}", link);
                INode newFolderNode = client.GetNodeFromLink(link);
                Console.WriteLine("Got node {0}, type {1}, size {2}, id {3}", newFolderNode.Name, newFolderNode.Type, newFolderNode.Size, newFolderNode.Id);
            }
            catch(Exception e)
            {
                Console.WriteLine("Caught exception type {0}: ({1}){2}{3}", e.GetType().Name, e.Message, Environment.NewLine, e.StackTrace);
            }
            client.Logout();
        }
    }
}

The link references a folder so you should use GetNodeSFromLink() method instead.
I will update the library to throw a meaningful exception when GetNode(s)FromLink are called with incorrect url

Thanks, still having problems though.
This code with this link
https://mega.nz/folder/L1xlRRAL#I5Lq0N5aUBT4dyLgp0QPFg
shows

Got node Attribute deserialization failed: Unexpected character encountered while parsing value: (. Path '', line 0, position 0., type File, size 507568, id 68BWELLS

Both the file and folder are named AMlNVS0u1Co0STJw0CrOyHBTSMtLUcvPLHDML1fwVE9LUVYsMFUwydNNSwgoSAIL.
Trying to access the link via web browser shows 'Invalid decryption key' but that's the link that was generated by GetDownloadLink and is the one Mega shows.
