Have there been updates made to the response objects from the Model Derivative API as we are having issues mapping the responses from requests for 3D models back into the Manife
I got what's wrong with the issue. The response of Get Manifest endpoint did changed a bit recently. There will a property database node aside the geometry nodes for Revit generated manifest. So one new role is 'Autodesk.CloudPlatform.PropertyDatabase'. While the old JAVA object ManifestChildren.JAVA does not declare the role. which caused the failure.
To fix it, you can simply add the new role in ManifestChildren.JAVA e.g.
i have requested a commit for JAVA SDK. you could modify it directly at your side if you merge the SDK source code to your project.
Hope this helps.
