Unsupported config option for services.db: 'platform'

[cleargoal]

I tried to start docker-compose up -d and got next error:

docker-compose up -d
ERROR: The Compose file './docker-compose.yml' is invalid because:
Unsupported config option for services.db: 'platform'

Help me, please.
What do I need to edit in this?
My system is Ubuntu 20.04
