                                         Throwable error)
```
    Called when an error is encountered.
    
    Parameters:
    
    event - The event of where this error occurred.
    
    error - The error encountered. It should be noted that this throwable will be a subclass of CommandException if an error was due to end-user error, and not an internal issue. As a result it will usually contain a user-friendly message which can simply be reported to the author of the message attempting to invoke a command.
