Почему сыпятся ошибки в nginx, при запуске python скрипта?

Решил сделать простенькую веб-морду для скрипта, которым будут пользоваться два с половиной человека.
Нагуглил про существование CGI и решил настроить.

Для примера простой python скрипт, который выводит в stdout:
  • директорию, откуда запущен скрипт
  • переменные окружения

/home/nonpriv/cgi/cgi-bin/test.py
#!/usr/bin/env python3.7
"""

"""

import os

print("Content-type: text/html\n")
print(f"""
    <!DOCTYPE html>
    <html lang="ru">
    <head>
    <meta charset="UTF-8">
    <title>WEB-helper</title>
    <link rel="stylesheet" href="style.css">
    </head>
    <body>
    <main>""")
# директория, откуда запускается скрипт
print(os.getcwd() + '<br>')
# вывод переменных окружения
for key in os.environ.keys():
    print(f"""
        <b>{key}: </b>{os.environ[key]}<br>
        """)
print(f"""
    </main>
    </body>
    </html>
    """)


Установленный Nginx с fcgiwrap, с таким конфигом:

Вообще, скрипт работает, получил то, что хотел.
Вывод скрипта в вебе:

...и т.д.



Меня напрягает ошибки в логах, почему они появляются?
DOCUMENT_ROOT and SCRIPT_NAME ведь переданы конфигу.
