Autodesk.CloudPlatform.PropertyDatabase missing in ManifestChildren.RoleEnum

[astuy]

I usually call DynamicJsonResponse.ToObject<T>() on api responses.

For DerivativeApi.GetManifest there is a problem: During translating an SVF calling GetManifestAsync() with status InProgress everything is fine. But when status is Success, i get a child with role Autodesk.Cloudplatform.PropertyDatabase (see screenshot), which leads to JsonSerializationException.

ManifestChildren.RoleEnum is missing the role.

I am translating a zipped Inventor assembly to SVF:

public async Task<Job> MyTranslateAsync(ObjectDetails objectDetails, string rootFilename)
{
    var input = new JobPayloadInput(objectDetails.ObjectId.ToBase64());
    if (objectDetails.ObjectId.EndsWith(".zip"))
    {
        input.CompressedUrn = true;
        input.RootFilename = rootFilename;
    }

    var output = new JobPayloadOutput(new List<JobPayloadItem>
    {
        new JobPayloadItem(JobPayloadItem.TypeEnum.Svf, new List<JobPayloadItem.ViewsEnum>
        {
            JobPayloadItem.ViewsEnum._2d,
            JobPayloadItem.ViewsEnum._3d
        })
    })
    {
        Destination = new JobPayloadDestination(JobPayloadDestination.RegionEnum.EMEA)
    };

    var job = new JobPayload(input, output);

    DynamicJsonResponse response = await _derivativesApi.TranslateAsync(job, true);
    return response.ToObject<Job>();
}

public async Task<Manifest> MyGetManifestAsync(string urn)
{
    DynamicJsonResponse response = await _derivativesApi.GetManifestAsync(urn);
    return response.ToObject<Manifest>();
}
