Thanks for the follow up. Try returning `false` from your
COMMAND_ENTRY_COMMAND handler. That should hide the command entry in
ncurses on KEY_ENTER.

If an event handler explicitly returns a boolean (either true or false, it
does not matter) then event propagation stops, subsequent handlers like
the Lua command handler is not run (so you won't see the error you
describe), and lL_event will return FALSE, allowing the entry to close.
