The error in the debug log is actually an unrelated symptom - the reason sweeps (from aetheryte/ferry) were not working at the time of posting was because the network opcode had not yet been updated for v6.11a.

I'll leave this issue open to track the websocket error (the one the attached error relates to), but the presence of this in the log does not actually effect the functionality of the plugin (for reasons beyond my comprehension).
