Я получаю эту ошибку. Исключение игнорируется в: <_io.TextIOWrapper name='<stdout>' mode='w'coding='cp1252'> OSError: [E ⇐ Python

Я помещаю несколько файлов журналов в скрипт Python, который затем передаю в голову следующим образом:

Код: Выделить всё

cat *mongodb.log.* | python jsonFetcher.py -b 20240101000000 -e 20250101000000 | head

вывод следующий: в конце я получаю ошибку. Я не получаю сообщение об ошибке при подключении к другому скрипту Python:

Похоже, что все мои исследования указывают на именование каталогов в Windows, хотя я не пишу ни в какие файлы
