I’m attempting to set up a local Debian mirror using the debmirror utility. Initially, I define the necessary variables and then execute the following commands. While it works perfectly for Debian ( http://deb.debian.org/debian/ ), But facing an issue when syncing Debian-Security ( http://deb.debian.org/debian-security/)

1. Create mirror for Debian ( http://deb.debian.org/debian/):

# VARIABLES:
root@debian12vm:~# EXCL="--exclude=-dbg_ --exclude=debian-installer-netboot-images --include=libc6-dbg"
DEBUG="-v"
ARCH=amd64
DIST=bookworm,bookworm-backports
DEST_DIR=${DEST_DIR:-"/var/lib/debian/samadhan-debmirror"}
SECT="--section main,contrib,non-free"
ALLOPT="$DEBUG --state-cache-days=100 --ignore-missing-release --ignore-release-gpg --passive --nosource --arch=$ARCH"
HOST="deb.debian.org"
DEFOPT="--keyring /usr/share/keyrings/debian-archive-keyring.gpg --method=http --rsync-extra=none --diff=none $ALLOPT --host=$HOST --dist=$DIST $SECT"
HTTP_MIRROR_DIR="/var/www/html/debmirror"

# COMMAND : 
root@debian12vm:~# debmirror $EXCL $DEST_DIR/debian $DEFOPT --getcontents

Actual and expected result: with this approach, I am able to create a Debian mirror successfully.:

2. Create mirror for Debian-Security ( http://deb.debian.org/debian-security/):

# VARIABLES
root@debian12vm:~# EXCL="--exclude=-dbg_ --exclude=debian-installer-netboot-images --include=libc6-dbg"
DEBUG="-v"
ARCH=amd64
DIST=bookworm,bookworm-backports
DEST_DIR=${DEST_DIR:-"/var/lib/debian/samadhan-debmirror"}
SECT="--section main,contrib,non-free"
ALLOPT="$DEBUG --state-cache-days=100 --ignore-missing-release --ignore-release-gpg --passive --nosource --arch=$ARCH"
HOST="deb.debian.org"
DEFOPT="--keyring /usr/share/keyrings/debian-archive-keyring.gpg --method=http --rsync-extra=none --diff=none $ALLOPT --host=$HOST --dist=$DIST $SECT"
HTTP_MIRROR_DIR="/var/www/html/debmirror"

# COMMAND:
root@debian12vm:~# debmirror --keyring /usr/share/keyrings/debian-archive-keyring.gpg --method=http $EXCL $DEST_DIR/debian-security $ALLOPT --host=${HOST} -r debian-security $SECT -d bookworm/updates

Actual Result: with this approach, I am unable to create a Debian-Security mirror:
