Autodesk Forge: WorkItem failing due to AppPackage Issues - autodesk-forge

Question

My AppPackage fails to load, and I'm unable to find the exact answer in the documentation or by the error message/code.
I tested the bundle by unzipping it into the "C:\Program Files\Autodesk\ApplicationPlugins" on my local machine, and it runs/loads as expected.
The AppPackage indicates that it is created successfully, which I'm sure is the most up-to-date version.
The addin is a .NET DLL file.

Make sure to double check how you zipped the AppPackage you uploaded. If you look inside your zip file, make sure you have a folder with the name PACKAGE_NAME.bundle and the PackageContents.XML file is inside that PACKAGE_NAME.bundle folder.
