VTOY_TEXT_MENU_VER in grub.cfg not working?

[mrplick]

at end of all_in_one.sh I get some errors - see screenshot.
It is does not affect the  .zip file, but I just wondered if there is a problem in the sh file or maybe I am missing something?
P.S. Still not found easter egg

Did you ever get an answer for the errors in the screenshot.
I am also getting the same errors.  no such file or directory for /ISO_TMP/EFI/ventoy/ventoy.gz
As for the Xorriso cmd not found.  I installed the Xorriso package.
I get the same errors in 1.31 and 1.32 when making the live cd.
