1 week ago Thanks for raising this @tbithell
I believe this is caused by this PR - https://github.com/microsoftgraph/msgraph-sdk-dotnet-core/pull/903 that changes the reflection usage in library and looks like this affects BaseDeltaFunctionResponse model as it does not contain a Value property(it is added by derived instances).
Ideally, using BaseDeltaFunctionResponse as the type parameter would be incorrect as the collection property of the response will have no type/property information to be deserialized into and would cause problems.
Out of curiosity does this work out for you when you use the DeltaGetResponse as the type parameter instead? Is there a specific reason to use the base class here?

Describe the bug
This code works in 5.56.1 and earlier, but breaks in 5.57 with - System.ArgumentException : The Parsable does not contain a collection property
`var pageIterator = PageIterator<DriveItem, BaseDeltaFunctionResponse>.CreatePageIterator( appGraphServiceClient, deltaGetResponse, (driveItem) => { allDriveItems.Add(driveItem); return true; }, (request) => { deltaToken = DeltaHttpHelper.GetQueryStringValueFromURI(request.URI.AbsoluteUri, Utils.Constants.Token); return request; });
await pageIterator.IterateAsync();`
Expected behavior
My integration tests should continue to work properly as they did before upgraded to 5.57
How to reproduce
After getting DriveItem DeltaQuery results create a pageiterator with the following code in 5.56.1 and then again in 5.57. It will work fine in 5.56.1 and fail in 5.57
`var pageIterator = PageIterator<DriveItem, BaseDeltaFunctionResponse>.CreatePageIterator( appGraphServiceClient, deltaGetResponse, (driveItem) => { allDriveItems.Add(driveItem); return true; }, (request) => { deltaToken = DeltaHttpHelper.GetQueryStringValueFromURI(request.URI.AbsoluteUri, Utils.Constants.Token); return request; });
await pageIterator.IterateAsync();`
