Facing error in CRYPTROOT_ENABLE option with buster image for opi3

Dear All,
I am trying to prepare the rootfs for opi3 board with CRYPTROOT_ENABLE option to yes using below command but getting error as below. 

./compile.sh  BOARD=orangepi3 BRANCH=current RELEASE=buster BUILD_MINIMAL=yes BUILD_DESKTOP=no KERNEL_ONLY=no KERNEL_CONFIGURE=no COMPRESS_OUTPUTIMAGE=sha,gpg,img CLEAN_LEVEL=images OFFLINE_WORK=yes CRYPTROOT_ENABLE=yes CRYPTROOT_PASSPHRASE="MYSECRECTPASS" CRYPTROOT_SSH_UNLOCK=yes CRYPTROOT_SSH_UNLOCK_PORT=2222 CRYPTROOT_PARAMETERS="custom cryptsetup options"
