We recently upgraded to 2.10 as well and have hit this issue. When we turn off the producers we can correctly get partitioned stats but with any level of input the command fails. We are running these commands from the brokers (via CLI) and from the java client. We have business logic, alerts, and scaling around the backlog amount so this is definitely causing some issues for us. We're also using the matching client version.
