VSCode quick fix does not suggest imports from a Python package in the same workspace

Overview

I have a VSCode workspace which contains two directories. In one is my main application, in another is a common package used by this application and a couple of others.

  # main-app.code-workspace
  "folders": [
    {
      "path": "."
    },
    {
      "path": "../common/shared_package"
    }
  ],

I am able to import classes from the shared package if I manually type out the import string (from shared_package.utils.clock import SuperClock), but VSCode's quick-fix isn't offering any help with this.

1. Imports from other dependencies typically work with quick-fix (eg if I type trio I get an Auto-Import suggestion from VS Code)
2. Imports from within main-app also work fine with quick-fix
3. Manually typing out the import to pull in classes from shared_package is fine
4. Quick fix does not work with shared_package classes

Additional Info

1. This is a Python project which uses Poetry for dependency management
2. my pyproject.toml file includes this line

[tool.poetry.dependencies]
shared-hub-be = { path = "../common/shared_package", develop = true }

3. I think it might be a red herring, but I am seeing this error (and only this error) in output when I open VSCode

2024-08-01 10:50:48.793 [error] Error: spawn pixi ENOENT
    at Process.ChildProcess._handle.onexit (node:internal/child_process:286:19)
    at onErrorNT (node:internal/child_process:484:16)
    at processTicksAndRejections (node:internal/process/task_queues:82:21) {
  errno: -2,
  code: 'ENOENT',
  syscall: 'spawn pixi',
  path: 'pixi',
  spawnargs: [ '--version' ]
}

4. "python.languageServer": "Pylance" is set in workspace file

What have I tried so far

I did what any of us would do and spent 6 months manually typing out the import statements.

Beyond that I tried some back and forth with ChatGPT - it suggested

1. Add the following to both my VSCode settings file and the Workspace settings file.

"python.analysis.extraPaths": ["../common/shared_package"]

2. Update PYTHONPATH to include /absolute/path/to/common/shared_package
3. Try removing develop=true and then rerunning poetry install

None of this stuff helped and has now been reverted.
