Custom FreeBSD 14.3-RELEASE ISO fails to boot to OS

Hello,

I've exhausted myself trying to fix this problem for the past 4 days. x_x

I'm following the the FreeBSD docs/manpages (+docs from FreeBSD based 
flavors) related to building a 14.3-RELEASE ISO, which I succeeded but 
it fails at boot time.
The kernel boots fine as far as I can tell, but 'init.sh' fails at 
replicating the system image (system.img) to swap.

I'm using VirtualBox VM to test the ISO and gave it the following specs:

--Disk: 45GB
--RAM: 16GB
--CPU: 12C

The error shows up when this command finishes "dd 
if=/cdrom/data/system.img status=progress bs=1M | zfs recv -F livecd".

This error sounds like it's a corrupt file, but I verified the hash, 
plus I didn't download it from the wild web for it to be tempered with.

ERROR: cannot receive new filesystem stream: incomplete stream
        Enter full pathname of shell or RETURN for /rescue/sh:

When I hit [ENTER], I get "Cannot read termcap database; using dumb 
terminal settings." Then drops to '#' which is limited and some commands 
don't work due to "/tmp" not found.

Please let me know if I get provide any other info that can help fix 
this issue.

Thanks,
