That does not match "man 8 poudriere-jail":

     -m method        Specify which method to use to create the jail.  The
                      default is http.

                      . . .

                      null         This option can be used to import an
                                   existing directory that already contains an
                                   installed system.  The path must be
                                   specified with -M path.  It is expected
                                   that this directory be installed to with
                                   the following:

                                     # cd /usr/src
                                     # make installworld DESTDIR=PATH DB_FROM_SRC=1
                                     # make distrib-dirs DESTDIR=PATH DB_FROM_SRC=1
                                     # make distribution DESTDIR=PATH DB_FROM_SRC=1

                                   It will not be copied at the time of
                                   running “poudriere jail”.  Deleting the
                                   jail will attempt to revert any files
                                   changed by poudriere.

You may want a separate directory tree with content that
matches the documented criteria. That is what I have
always done.

I'll note that "man 8 poudriere" says:

. . .
   Create optional poudriere.conf
     You can also specify an optional poudriere.conf that is pulled in
     depending on the build.  Any of the following are allowed and will all be
     used in the order shown:

           /usr/local/etc/poudriere.d/poudriere.conf
           /usr/local/etc/poudriere.d/<setname>-poudriere.conf

What do you have for the content of:

/usr/local/etc/poudriere.conf

(or the like)?

/usr/local/etc/poudriere.conf.sample exists for
reference. Some of that is:

# Define to yes to build and stage as a regular user
# Default: yes, unless CCACHE_DIR is set and CCACHE_DIR_NON_ROOT_SAFE is not
# set.  Note that to use ccache with BUILD_AS_NON_ROOT you will need to
# use a non-shared CCACHE_DIR that is only built by PORTBUILD_USER and chowned
# to that user.  Then set CCACHE_DIR_NON_ROOT_SAFE to yes.
#BUILD_AS_NON_ROOT=no

# Define to the username and groupname to build as when BUILD_AS_NON_ROOT is yes.
# Default: nobody (uid PORTBUILD_UID)
#PORTBUILD_USER=nobody
#PORTBUILD_GROUP=nobody

# Define to the uid and gid to use for PORTBUILD_USER if the user does not
# already exist in the jail.
# Default: 65532
#PORTBUILD_UID=65534
#PORTBUILD_GID=65534

Are you happy with the documented defaults?

(Fair warning, I've always used
BUILD_AS_NON_ROOT=no so I've no experience.)
