Onion spits out error when typing messages - Debian 11

[WinsDominoes]

Hi ONION devs,

This morning, I was trying out the latest build of ONION from your CircleCI instance.
When I started the server, everything went nicely. But when I typed into the chat, the console spits out this error.

After typing 3 messages, I was kicked with the message "Invalid keep-alive ID". I couldn't remember the exact message.

Is there a possible fix for this? Or is it just because of my stupidity?

It appears to be an issue with #getPlayer():

Perhaps there wasn't a connection instance yet, though I'm not sure why that would be. I'll investigate this further :)
