"Error while copying content to a stream" while watching resources

[ShirmanDenis]

Describe the bug I using an extension method WatchAsync() for watching kubernetes resources. When server is closed the connection because the version used in request is too old (it doesn't really matter for what reason) I receive an exception:

Kubernetes C# SDK Client Version 15.0.1

Server Kubernetes Version 1.31.12

Dotnet Runtime Version net6

To Reproduce Use method for any resources with resourceVersion parameter and wait while server is close the connection

Expected behavior The extension method WatchAsync() returned without unhandled exceptions while the list or stream is empty.

Additional context I think the bug is here. Because in this place we expect the null string but exception will be thrown
