On my dev machine, I have a headless version of optimizely running.

In the cms when uploading an image (vf.jpg) it creates a apps\optimizely\App_Data\blobs\4f4864ab0dbd41aa8065dca34377ce24\47549b475bbe41bfb62a31b70a8e25a4.jpg file on the file system.

The image thumbnail does show a thumbnail version of the image. The image preview does not. It gives me 2 404's

http://localhost:8000/EPiServer/CMS/Content/globalassets/vf.jpg,,48?epieditmode=False

And

http://localhost:8000/EPiServer/CMS/Content/globalassets/vf.jpg,,48?epieditmode=False and http://localhost:8000/EPiServer/CMS/ImageEditor/GetImage?epieditmode=true&zoom=100&quality=100&img=http://localhost:8000/EPiServer/CMS/Content/globalassets/vf.jpg,,47?epieditmode=False&commands=

Also calling http://localhost:8000/EPiServer/CMS/Content/globalassets/vf.jpg from the browser gives a 404.

In the startup.cs I use:

app.UseStaticFiles(); // Existing static files middleware

    // Add the new static files middleware to serve files from the blob storage folder
    app.UseStaticFiles(new StaticFileOptions
    {
        FileProvider = new BlobFileProvider(
            Path.Combine(env.ContentRootPath, "App_Data", "blobs")),
        RequestPath = "/EPiServer/CMS/Content/globalassets"
    });

and blobfileprovider looking like:

using Microsoft.Extensions.FileProviders;
using Microsoft.Extensions.Primitives;
using System;
using System.IO;

public class BlobFileProvider : IFileProvider
{
  private readonly string _root;

  public BlobFileProvider(string root)
  {
    _root = root;
  }

  public IDirectoryContents GetDirectoryContents(string subpath)
  {
    return new PhysicalFileProvider(_root).GetDirectoryContents(subpath);
  }

  public IFileInfo GetFileInfo(string subpath)
  {
    string[] pathSegments = subpath.Split(new[] { "/globalassets/" }, StringSplitOptions.RemoveEmptyEntries);

    if (pathSegments.Length != 1)
    {
      return new NotFoundFileInfo(subpath);
    }

    string newPath = Path.Combine(_root, pathSegments[0].Replace('/', '\\'));
    return new PhysicalFileProvider(Path.GetDirectoryName(newPath)).GetFileInfo(Path.GetFileName(newPath));
  }

  public IChangeToken Watch(string filter)
  {
    return new PhysicalFileProvider(_root).Watch(filter);
  }

  IChangeToken IFileProvider.Watch(string filter)
  {
    throw new NotImplementedException();
  }
}

Im new to optimizely (headless). Any idea what im doing wrong?
