Building a poudriere for pfsense 23.01

Please pardon my inexperience with git.

When I built a poudriere jail to build packages for 22.05 I used:

     poudriere jail -x -u -j 12pfsense -a arm64.aarch64 -m git+https \
         -v 12.3-STABLE@5f81a4619dcf

I got the git hash from here:

     https://docs.netgate.com/pfsense/en/latest/releases/versions.html

Now I want to build a jail for 23.01 and this page says the version is 
14.0-CURRENT@aec9453fec7 but poudriere tells me that branch is not 
found... I was able to clone https://git.freebsd.org/src.git to a 
scratch directory and can see hash 5f81a4619dcf in the log in branch 
"main" but main@aec9453fec7 and head@aec9453fec7 do not work when trying 
to build a poudriere jail.

This is the last thing I tried, what am I doing wrong?

     poudriere jail -x -c -j 14pfsense -a arm64.aarch64 -m git+https \
         -U https://git.freebsd.org/src.git -v 14.0-CURRENT@aec9453fec7

(The last time I tried running CURRENT on a test box I got stuck at 
building packages for it, I think my problem was the same as this...)
