Hey Thomas, The issue wouldn't be that generation would fail - the idea is that due to having recompiled the API against different classes for V2, the old client might not be sending requests in the way expected. Could you try to load the updated client library into a client machine and see if the same error persists with the new version of the library? I'm continuing to work on reproducing this issue on my own side.
