Hello,
I'm developing a Django project and a puzzling error has popped up, while
using Selenium.
- The Selenium tests run smoothly and pass, despite this error message
- The unitary tests as well.
- When I launch the server, the project runs fine, as well...
Here is the Selenium starting point:
{{{
class CustomUserTest(LiveServerTestCase):
fixtures = ['users.json']

@classmethod
def setUpClass(cls):
super().setUpClass()
cls.browser = Firefox()
cls.browser.implicitly_wait(10)

@classmethod
def tearDownClass(cls):
cls.browser.quit()
super().tearDownClass()

def test_plaid_10_authenticate_on_the_website(self):
self.browser.get(os.path.join(self.live_server_url, ''))
}}}

There is only a puzzling error message, which does not seem being related
to my project, as everything else is ok.
Here is an excerpts of the issue:

{{{
File "Users/myname/Documents/myfolder/myproject/venv/lib/python3.7/site-
packages/django/test/testcases.py", line 1417, in serve
return serve(request, final_rel_path,
document_root=self.get_base_dir())
File "Users/myname/Documents/myfolder/myproject/venv/lib/python3.7/site-
packages/django/views/static.py", line 36, in serve
fullpath = Path(safe_join(document_root, path))
File "Users/myname/Documents/myfolder/myproject/venv/lib/python3.7/site-
packages/django/utils/_os.py", line 17, in safe_join
final_path = abspath(join(base, *paths))
File
"/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/posixpath.py",
line 80, in join
a = os.fspath(a)
TypeError: expected str, bytes or os.PathLike object, not NoneType
[09/Apr/2021 07:13:07,948] - Broken pipe from ('127.0.0.1', 54981)
}}}
Here is a copy of my requirements.txt:
{{{
asgiref==3.3.4
certifi==2020.12.5
chardet==4.0.0
coverage==5.5
Django==3.2
django-registration-redux==2.9
idna==2.10
psycopg2==2.8.6
python-dotenv==0.15.0

requests==2.25.1
selenium==3.141.0
sqlparse==0.4.1

}}}

Hope this bug may raise your interest !
Kind regards.

Thanks for this report, however I don't think you've explained the issue
in enough detail to confirm a bug in Django. Please reopen the ticket if
you can debug your issue and provide more details or a sample project.
