dart-sdk feature is broken

[kevin-sakemaer]

Here is the content of my devcontainer.json it come from here

{
    "image": "mcr.microsoft.com/devcontainers/base:debian",
    // 🧰 Add mixins and addons with devcontainer features! For a complete list
    // of features, check out containers.dev/features.
    "features": {
        "ghcr.io/devcontainers-community/features/dart-sdk": {}
    },
    // 👷‍♂️ Use 'postCreateCommand' to run commands after the container is created.
    // "postCreateCommand": "dart --version",
}

but when i reopen the current folder in a container I got this log in creation.log.
