IndexOutBoundException when packing scalar value with ByteArrayPacker

[theolivenbaum]

I'm getting the following exception when trying to serialize an object containing a Dictionary<int,int>, using PackSingleObjectAsync(object):

Unhandled Exception: System.AggregateException: One or more errors occurred. ---> System.IndexOutOfRangeException: Index was outside the bounds of the array.

I'm getting a similar error, but with a different StackTrack:

Rolling back to Nuget 0.8.1 resolved the problem for me, so it looks like a bug with the latest release.

Thank you for reporting! I will investigate it soon.

I failed to reproduce this issue. Could you tell me repro code? It should be caused by specific class layout to serialize.

I'm trying to serialize a large .NET List of a simple POCO object:

@BuairtRi Thank you!

[yfakariya]

I found a workaround. You should avoid this issue use Pack instead of PackSingleObject.

[yfakariya]

I've fixed this issue and released 0.9.1 now. Please try it.

[BuairtRi]

Thanks! I'll reinstall the update soon and deploy to see if it's all working.
