Internal error occured when attempting to do /isetentrance or /isetdestination

[docktacakez]

Also, when someone makes a party and goes into an existing portal, it goes nowhere. I am lost here. All my plugins are updated, so I don't know what the issue could be. (Also, I keep getting spam in the console with similar errors to when I try to make a portal). This is the log from the console. These errors appear when I attempt to do the commands in the title, or when players are doing random things (not related to the instance world).
