Docker-compose Error in yaml file

[grumpyprogrammingracoon]

Install on Raspberry Pi4 running current RaspiOS

running "docker-compose up -d" I get

"ERROR: Version in "./docker-compose.yml" is unsupported. You might be seeing this error because you're using the wrong Compose file version. Either specify a supported version (e.g "2.2" or "3.3") and place your service definitions under the services key, or omit the version key and place your service definitions at the root of the file to use version 1.
For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/"

I installed the latest bookworm PiOS image

cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 12 (bookworm)"
NAME="Debian GNU/Linux"
VERSION_ID="12"
VERSION="12 (bookworm)"
VERSION_CODENAME=bookworm
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

Did a sudo apt update && sudo apt install docker-compose -y and had no problem starting the container with sudo docker-compose up. What version of compose are you using?

docker-compose -v
docker-compose version 1.29.2, build unknown

Changed the version from 3.8 to 3.3 in the yml file and the container started.
