StatusObservedOur team will look into this soon, verify the cause and try to fix it in an upcoming release.
Why it happens
The repository was cloned successfully, but Docker Compose rejected its configuration before starting any containers. The docker-compose.yml contains a top-level app property that is not valid in the Compose schema being used. The expected application definition is typically under services.
