Hi @ravirahman,
I have the same issue when attaching using the UI.
When i open the project in WSL, this appears.
After clicking it, I get the message:
Failed to reopen folder in container: Failed to read devcontainer configuration

Also is there documentation on the format that cursor uses for their URI format?
