Disk encryption example does not work (version 5.5)

Hi. I copied all of commands from this section and pasted into a file tpm.sh:

#! /bin/sh
set -xe
mkdir -p tpm
cd tpm

dd if=/dev/urandom bs=1 count=32 status=none > pass.secret
tpm2_startauthsession -V -S session.ctx
tpm2_policypcr -V -Q -S session.ctx -l sha256:0 -L set2.pcr.policy
tpm2_flushcontext -V session.ctx
openssl genrsa -out signing_key_private.pem 2048

cat pass.secret | tpm2_create -V -g sha256 -u auth_pcr_seal_key.pub -r auth_pcr_seal_key.priv -i- -C prim.ctx -L authorized.policy

tpm2_unseal -p session:session.ctx -c 0x81010001
tpm2_flushcontext session.ctx

# clean up
cd -
ls -lash tpm/*
rm -rf tpm

After running the file, I get the following error:
