Subshell command in build options not executed

Bắt đầu bằng cách tái hiện vấn đề với ví dụ build.options trong devcontainer.json và trường hợp emptytestscript.sh, sau đó so sánh lệnh được tạo trong devContainersSpecCLI.js với cùng lệnh được chạy trong terminal. Theo dõi cách các tùy chọn build được truyền vào docker buildx; hoàn thành khi phép thay thế lệnh và các tùy chọn dựa trên dấu backtick hoạt động như mong đợi và build chấp nhận các đối số thu được.

I have devcontainer.json setup like this

"build": {
        "dockerfile": "${localWorkspaceFolder}/docker/development/Dockerfile",
        "context": "${localWorkspaceFolder}",
        "options": [
            "$(awk '{ sub (\"\\\\\\\\$\", \" \"); printf \" --build-arg %s\", $0  } END { print \"\"  }' ${localWorkspaceFolder}/.env)"
        ]
},

awk command in options should read specified .env file and create --build-arg for every one of them.

Unfortunately when i run build command i get this error.

But if I take command

docker buildx build --load --build-arg BUILDKIT_INLINE_CACHE=1 -f /tmp/devcontainercli-rijad/container-features/0.65.0-1724398400319/Dockerfile-with-features -t vsc-asx-ubuntu-627ff9ecdd16cefae9d376770411bccfd81a6bb640f586cfb01f9d12f1afe637 --target dev_containers_target_stage --no-cache --pull $(awk '{ sub ("\\\\$", " "); printf " --build-arg %s", $0 } END { print "" }' /home/rijad/asx-ubuntu/.env) --build-arg _DEV_CONTAINERS_BASE_IMAGE=dev_container_auto_added_stage_label /home/rijad/asx-ubuntu
and paste it in my terminal, it runs with no issue.

Also other ways of spawning subshell, like backticks do not work as well.

Even if i create empty test script with exec permissions and try

"options": [
    "$(${localWorkspaceFolder}/emptytestscript.sh)"
]

it ends up with same error.

I am running wsl Ubuntu on windows 10.
