Issues in vscode devcontainer

[michaelxswe]

devcontainer.json

{
    "name": "app",
    "dockerComposeFile": "../docker-compose.yml",
    "service": "app",
    "workspaceFolder": "/workspace",
	"customizations": {
    	"vscode": {
      	    "extensions": [
	        "ms-python.python",
		"charliermarsh.ruff"
	    ]
    	}
    }
}

Whenever I try to create a new file, pylance won't recognize the new file and cause import to fail

For example if I create a new file and try to import it from main.py, i will get the following error

Import "app.sub" could not be resolvedPylance[reportMissingImports]

Now if I reload the the ide window, import works as expected.

Does anyone know how I can resolve this?
