Hey,
While developing a small service grpc-curl, I found a small bug in
FieldDescriptor.IsPacked
that was throwing aNullReferenceException
that I had to workaround here:https://github.com/xoofx/grpc-curl/blob/f7bbe35af79713f278150b96ce51817807a06581/src/DynamicGrpc/DynamicMessageSerializer.cs#L434-L455
So this PR is a small bug fix. Though, I haven't found a test to update about it, not sure if we have any?
