poetry install --> not enough values to unpack

Question

I have my pyproject.toml file in the root of my project. It looks something like this (names changed for simplicity/discretion, but works the same):

[tool.poetry]
name = "controller_poc"
version = "0.1.0"
description = "Controller (API) POC"
license = "MIT"
authors = ["Felipe Freitas"]
readme = "README.md"
repository = "https://github.com/felipefreitassilva/..."
keywords = ["Controller", "POC"]

[tool.poetry.dependencies]
python = "^3.9"
fastapi = "0.103.1"
pylint = "2.17.6"
pydantic = "2.3.0"
uvicorn = "0.23.2"
python-multipart = "0.0.6"
httpx = "0.25.0"

sqlalchemy = {version = "2.0.20", extras = ["sqlite"]}
sqlalchemy_utils = "0.41.1"
pymysql = "1.0.2"

autopep8 = "2.0.4"
pytest = "7.4.2"
pytest-cov = "4.1.0"

[tool.poetry.scripts]
start = "app.main:start"
test = "pytest"
lint = "autopep8 --in-place --recursive ."

[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"

If I run poetry install from the root, all goes correctly:

C:\Users\Felipe\Controller_POC> poetry install
Skipping virtualenv creation, as specified in config file.
Installing dependencies from lock file

No dependencies to install or update

However, if I attempt to run the start command, like so:

C:\Users\Felipe\Controller_POC> poetry run start
Skipping virtualenv creation, as specified in config file.

No file/folder found for package controller-poc

It throws this error - which has nothing to do with the script itself, the script works normally (and looks like this) if it matters:

def start():
    """
    Run the application with uvicorn
    """
    from uvicorn import run
    run('app.main:app',
        reload=True,
        workers=1,
        host=settings.API_HOST,
        port=settings.API_PORT)


if __name__ == "__main__":
    start()

However, and this is where the problem occurs:

If I add the package, using pyproject's tool > packages option, like so:

pyproject.toml

...
keywords = ["Controller", "POC"]
packages=[{ include="app" }]

[tool.poetry.dependencies]
python = "^3.9"
...

and attempt to run poetry install again, it throws a new error

C:\Users\Felipe\Controller_POC> poetry install
Skipping virtualenv creation, as specified in config file.
Installing dependencies from lock file

No dependencies to install or update

Installing the current project: controller_poc (0.1.0)

not enough values to unpack (expected 2, got 1)

That being said, altough it "creates" this previously non existing error, it also fixes the start script:

C:\Users\Felipe\Controller_POC> poetry run start
Skipping virtualenv creation, as specified in config file.
INFO:     Will watch for changes in these directories: ['C:\\Users\\Felipe\\Controller_POC']
INFO:     Uvicorn running on http://0.0.0.0:8000 (Press CTRL+C to quit)
INFO:     Started reloader process [3336] using StatReload
INFO:     Started server process [7372]
INFO:     Waiting for application startup.
INFO:     Application startup complete.

I have no idea why this "seesaw" effect happens, and I have tried and tried through many forums, documentations and other sources, but I can't seem to find what is happening

I'm somewhat new to python, perhaps it doesn't work as I expect and I should change completely to another tool. I read about poethepoet, but don't know weather it is secure and if it would do what I intended.

If someone could give me any directions, I would deeply appreciate it
