update.update sometimes gives me the error message "Fake Middleware object has no attribute call_sync"
I'm not quite sure what this error means but I see it sometimes when I try to update but then if I try again the update will sometimes succeed. It is kind of hit or miss as to whether it will happen so I understand if you have a hard time reproducing it but I will gladly help in whatever way to figure this out. I attached a debug immediately after this error happened so maybe that will help you figure out why it is doing this. Let me know how I can help.
