[Python] 'NoneType' object has no attribute 'group' building a package with click

Hello I am trying to building a python package I have the following folder structure

.
├── Dockerfile
├── entrypoint.sh
├── Pipfile
├── Pipfile.lock
├── setup.py
└── vms-backup
├── commands
│ ├── __init__.py
│ ├── to_csv.py
│ ├── to_sql.py
│ └── upload_to_s3.py
└── __init__.py


the setup.py contains the following code:

from setuptools import setup, find_packages
import pipfile

pf = pipfile.load("Pipfile")

setup(
name="vms-backup",
version="1.0.0",
packages=find_packages(exclude=["tests"]),
python_requires="==3.8.13",
install_requires=["click"],
entry_points="""
[console_scripts]
vms-backup=vms-backup:cli
""",
)


and vms-backup/.init.py

import click
from commands import to_csv, to_sql, upload_to_s3


@click.group()
def cli():
pass


cli.add_command(to_csv)
cli.add_command(to_sql)
cli.add_command(upload_to_s3)


if __name__ == "__main__":
cli()


The code works perfectly if I execute, but when executing pip install -e . in order to test the entry_points I got the following output:

Preparing metadata (setup.py) ... error
error: subprocess-exited-with-error

× python setup.py egg_info did not run successfully.
│ exit code: 1
╰─> [1 lines of output]
error in vms-backup setup command: 'NoneType' object has no attribute 'group'
[end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

× Encountered error while generating package metadata.
╰─> See above for output.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.


Any idea about what is wrong with the code?

Thanks

EDIT

If I execute inside a dockerfile the error change:

backup_1 | Obtaining file:///usr/app
