`undefined` in docker-compose.devcontainer.build-*.yml

[hankei6km]

I am trying with the following repository.

• devcontainer.json use docker compose
• A workflow is run with GitHub Actions

https://github.com/hankei6km/test-devcontainers-cli-compose

cli

Using @devcontainers/cli directly from within the workflow will succeed.

https://github.com/hankei6km/test-devcontainers-cli-compose/runs/6874333436?check_suite_focus=true

ci

Using devcontainers/[email protected] will result in an error.

I've just started seeing this after doing some changes that resulted in the container getting updated. Is there a resolution or workaround?

devcontainers/ci latest version also works with Dev Containers using docker-compose.
