Describe the Bug
When trying to relaunc a folder in a dev container with the given configuration, it doesn’t work.
Specifically tested on Windows WSL2.
There’s an issue with the paths.
Steps to Reproduce
Open a folder in cursor. Under the directory .devcontainer create a devcontainer.json file:
{
"name": "Python 3",
"image": "mcr.microsoft.com/devcontainers/python:1-3.12-bullseye",
"features": {
"ghcr.io/devcontainers/features/git:1": {
"ppa": true,
"version": "latest"
},
"ghcr.io/nikobockerman/devcontainer-features/poetry-persistent-cache:1": {},
"ghcr.io/devcontainers-extra/features/poetry:2": {
"version": "latest"
}
}
}
Expected Behavior
The folder should reopen in the dev container but instead it just errors.

Does this stop you from using Cursor
Yes - Cursor is unusable
