pgBackrest Error : authentication method 10 not supported

Hello,

I am getting an error message " authentication method 10 not supported"
while trying to create stanza on postgres14 after upgrading postgres from
v.10 to Postgres v.14.

I am using pgbackrest version: v.43 and the scram-sha-256 for hba
authentication.

pgbackrest.conf entry:

cat /etc/pgbackrest/pgbackrest.conf

[global]
repo1-path=/opt/backups
repo1-retention-full=2

[test14]
pg1-path=/opt/PostgreSQL-14/data
pg1-port=5432
pg1-user=postgres
pg1-socket-path=/tmp

Error Message:
