"Add to devcontainer.json" does not work inside the container

[ThePlenkov]

Type: Bug

I work in a devcontainer and I want to install the extension. Not to install it every time - I want to use "Add to devcontainer.json" task. Unluckily it does nothing. So when I press it - my devcontainer.json is not updated. When I open same repo from WSL - it works. So I guess it's only related to a case when I use this function from inside a devcontainer. My devcontainer config is trully minimalistic - just the image name:

{
  "name": "Node.js & TypeScript",
  "image": "mcr.microsoft.com/devcontainers/typescript-node:1-22-bookworm",
}

I consider it as a bug - why can't it use just a relative path and update devcontainer.json?

Could you please have a look?
