Critical uncaught exception after update

Hi there,
I updated the plugin to the latest version 3.2.9 today.
After the update I was entering tracking numbers and a few times I got this fatal error.
I was using “set order status to completed” and the status for those orders was a custom status (“awaiting dispatch”)
