open source – How to Upload a Zip File and Create an AppBundle in Autodesk Forge Design Automation SDK?

I am trying to upload a zip file to Autodesk Forge’s Object Storage Service (OSS) and then use it to create an AppBundle for Design Automation. While I successfully upload the file and create the AppBundle, the package URL linked to the AppBundle always gives a NoSuchKey error when accessed.

Here’s the relevant part of my code:

var auth = new TwoLeggedApi();

dynamic tokenResponse = await auth.AuthenticateAsync(
    ClientId,
    ClientSecret,
    oAuthConstants.CLIENT_CREDENTIALS,
    [Scope.DataRead, Scope.DataWrite]
);

var objectsApi = new ObjectsApi { Configuration = { AccessToken = tokenResponse.access_token; } };

using var fileStream = new FileStream(zipFilePath, FileMode.Open, FileAccess.Read);

dynamic response = await objectsApi.UploadObjectAsync(
    bucketKey,
    objectKey,
    (int)fileStream.Length,
    fileStream,
    "application/zip"
);

string ossObjectUrl = $"https://developer.api.autodesk.com/oss/v2/buckets/{bucketKey}/objects/{objectKey}";

string fullyQualifiedId = $"{_account}.{bundleId}";
var newVersion = new AppBundle
{
    Id = fullyQualifiedId,
    Engine = $"Autodesk.Revit+{yearVersion}",
    Package = ossObjectUrl,
    Description = $"App bundle for Revit {yearVersion}",
};

AppBundle bundle = await _daClient.CreateAppBundleAsync(newVersion);
// package URL is valid
// after creating an alias and fetching the AppBundle again, the package url is invalid

The AppBundle is created successfully, but when I set an alias and try to access the package URL, I get an error:

NoSuchKey
The specified key does not exist.
