Problem Installing Sametime Premium 12 on Centos 7.9

I get the following error running the ./install.sh script.

ERROR: The Compose file './docker-compose.yml' is invalid because:
Unsupported config option for services.hcl-stm-outlook: 'profiles'

Docker egine version 20.10 and docker-compose version 1.26.2.

Any ideas what could cause that error?

You need to upgrade docker-compose to the latest - atleast 1.29.x
