Debugger Gets Stuck When Trying to Debug Rust Inside a Dev Container

[mcmah309]

The debugger gets stuck when trying to debug rust container inside a dev container. Here's an example, it stays like this forever

.devcontainer

{
    "name": "rust_dev",
    "image": "rust_dev",
    "customizations": {
        "vscode": {
            "extensions": [
                "rust-lang.rust-analyzer",
                "serayuzgur.crates",
                "vadimcn.vscode-lldb"
            ]
        }
    },
    "mounts": [
        // rust
        "source=/home/henry/.local/share/containers/storage/volumes/rust_dev/_data/root/.cargo,target=/root/.cargo,type=bind",
        "source=/home/henry/.local/share/containers/storage/volumes/rust_dev/_data/root/.rustup,target=/root/.rustup,type=bind"
    ],
    "runArgs": [
        "--net=host",
    ],
    "remoteUser": "root"
}

Compiling with cargo and running with vscode works fine.

The output that is notable is this

Warning: codelldb.cargo tasks are unavailable in the current environment.

I was able to fix this issue by using another rust image. It would be nice if Warning: codelldb.cargo tasks are unavailable in the current environment. was more specific and didn't cause vscode to hang indefinitely without being able to be cancelled.

Same problem here. Docker image built from alpine:3.18 . Rust version 1.77.2 installed with rustup 1.27.0
