Trying to load Folder from File

[ivonool]

Hi

I'm not sure if it is a bug or I'm doing something wrong anyway I'm trying to load Folder for a File. I have a file UniqueId and need to load all the files in that folder. Current code:

var mainFile = await context.Web.GetFileByIdAsync(fileGuid), f => f.ListId, f => f.ListItemAllFields);
var mainFileItem = await mainFile.ListItemAllFields.GetAsync(p => p.Folder, p => p.UniqueId);
var folder = mainFile.ListItemAllFields.Folder;
await folder.LoadAsync(f => f.Files);

Whenever last line is executed, I get the error:

PnP.Core.ClientException: Unresolved tokens found in API call https://xyz.sharepoint.com/sites/xyz/_api/Web/Lists(guid'{List.Id}')/Items(63)/Folder?$select=UniqueId%2cFiles&$expand=Files

So for some reason List Guid seems to be missing in the URL. Any ideas? Using version 1.9.0

@ivonool : below works for me:

IFile testDocumentLoadedById = await context.Web.GetFileByIdAsync(Guid.Parse("{0c89259b-af52-4c78-aa9d-b6385ac563ca}"),  p => p.ServerRelativeUrl);

var folderPath = Path.GetDirectoryName(testDocumentLoadedById.ServerRelativeUrl).Replace("\\", "/");

IFolder folder = await context.Web.GetFolderByServerRelativeUrlAsync(folderPath, p=>p.Files);

foreach (var file in folder.Files.AsRequested())
{
    // Use the file
}

@jansenbe thanks, your provided code works for me too. Anyway wondering, if in my previous code did I do something wrong, that list Id wasn't replaced in the REST query or is it a bug.

@ivonool , is the file you're loading hosted in a document library?
