Unknown options: super *** Failed to Launch an Instance - MariaDB v1.2.2 postConfigure on AWS AMI

Good day,

I am following instructions here (https://mariadb.com/kb/en/library/installing-and-configuring-a-columnstore-system-using-the-amazon-ami/#mariadb-columnstore-post-install-script-postconfigure).

When I get to below postConfigure step

Create Instance for um1 [y,n] > y

I get:

Unknown options: super
'*** Failed to Launch an Instance for um1, will retry up to 5 times
usage: aws [options] <command> <subcommand> [<subcommand> ...] [parameters]
To see help text, you can run:
aws help
aws <command> help
aws <command> <subcommand> help

It tries for 5 times and then exits.

Many thanks.
