Network Service has is not JSON serializable issue

I went from googleads 10 to the newest version of ad manager and now a simple get of all networks associated with a service email account does not work anymore. I get a serialization error with the response. This was not an issue before upgrading. If I downgrade again everything goes back to normal. Is there something I need to do? I've even printed the entire object I'm attempting the json.dumps on and if I copy that into a new script and place it into a json.dumps function it works so there doesn't appear to be anything wrong with the list I'm passing in. This also make it very hard to debug this issue.
Error:
