This is a confirmed bug that is most reproducible with kappa and crane dbs. Looking at the backtrace, the fork command is not getting the expected message from the addon:add command to parse. For production dbs, the wait for this message can be 5-10 seconds, and if fork is not waiting, it will fail. dev/basic and ronin up dbs are able to return faster, but may also fail.
