Unable to specify the installation of the current directory, which causes a ModuleNotFoundError

I am trying to deploy a Streamlit dashboard to Connect, but get an error.

Setup

I have the following directory structure:

dashboard
`-- app.py         # imports from my_awesome_package
src
|-- my_awesome_package
|    |-- data.py
|    `-- views.py
requirements.txt   # Specify requirements for my_awesome_package
pyproject.toml     # Specify installation of my_awesome_package

Deployment

Deployment happens in two steps:

1. rsconnect write-manifest streamlit --entrypoint=dashboard/app.py .
2. rsconnect deploy manifest manifest.json --title "My Dashboard"

The Error

Once deployed, I open the application and get the following error:

ModuleNotFoundError: No module named 'my_awesome_package'

The issue

I believe the issue is as follows: The connect server does not install packages from the local directory (through setup.py or pyproject.toml.), but only what is in requirements. In the manifest.json, the files from my_awesome_package are specified, but they cannot be found because the package has not been installed.

Question

How can I specify through rsconnect that the current directory should also be installed? Could this be an update to the manifest, or is there another way of doing it?

Start by reproducing the deployment with dashboard/app.py, requirements.txt, pyproject.toml, and the two rsconnect commands shown. Inspect manifest.json to determine how the local package is represented and compare that with the deployment behavior. Done means the deployed dashboard can import my_awesome_package from the current directory without relying on manually copying package files.
