I’m on Windows 11 with docker running in WSL2.  
On Windows I’m using Visual Studio Code with Dev Container extension.  
I have created a folder `julia` with a `.devcontainer` subfolder containining a `devcontainer.json` like the following:

```julia
{
    "name": "Julia",
    "image": "mcr.microsoft.com/devcontainers/base:ubuntu",
    "features": {
        "ghcr.io/julialang/devcontainer-features/julia:1": {
            "channel": "release"
        },
        "ghcr.io/devcontainers/features/common-utils:2": {
            "installZsh": "true",
            "configureZshAsDefaultShell": true,
            "username": "vscode",
            "upgradePackages": "true"
        }
    },
    
    "customizations": {
        "vscode": {
            "extensions": [
                "julialang.language-julia"
            ]
        }
    },
    
    "postCreateCommand": "julia-activate"    
}

```

Once I open the `julia` folder in Visual Studio Code, after it opens the container, I get the following error:

```julia
Running the postCreateCommand from Feature 'ghcr.io/julialang/devcontainer-features/julia:1'...

[7271 ms] Start: Run in container: /bin/sh -c /usr/local/julia-devcontainer-features/postcreate.jl

Done. Press any key to close the terminal.

```

I’m running into [this problem](https://github.com/microsoft/vscode-remote-release/issues/7958): I have the same issue when building `b-data`’s project
