Почему я не могу создавать таблицы? ⇐ Python

[Anonymous]

Я делаю серверную часть с помощью postgresql. Важно отметить, что ChatGPT написал за меня мой код. Имя проекта — greenid, а также имя моей базы данных в postgresql. У меня PostgreSQL 16-й версии. Так что же означает эта ошибка? Что мне нужно сделать? Мой .env:
DB_USER=postgres
DB_PASSWORD=test123
DB_HOST=localhost
DB_PORT=5432
DB_NAME=greenid

Также эта ошибка возникла при попытке запустить init_db.py:
from database import Base, engine
import models
Base.metadata.create_all(bind=engine)
print("Таблицы успешно созданы")

и, возможно, если вам нужен data.py:
import os
from dotenv import load_dotenv
from urllib.parse import quote_plus
from sqlalchemy import create_engine
from sqlalchemy.orm import declarative_base

# Загружаем .env
load_dotenv()
print("DB_PASSWORD =", os.getenv("DB_PASSWORD"))

# Получаем значения
DB_USER = os.getenv("DB_USER")
DB_PASSWORD_RAW = os.getenv("DB_PASSWORD")
DB_HOST = os.getenv("DB_HOST")
DB_PORT = os.getenv("DB_PORT")
DB_NAME = os.getenv("DB_NAME")

# Проверка (ОБЯЗАТЕЛЬНО)
if DB_PASSWORD_RAW is None:
raise RuntimeError(" DB_PASSWORD не найден. Проверь файл .env")

# Кодируем пароль
DB_PASSWORD = quote_plus(DB_PASSWORD_RAW)

DATABASE_URL = (
f"postgresql+psycopg2://{DB_USER}:{DB_PASSWORD}"
f"@{DB_HOST}:{DB_PORT}/{DB_NAME}"
)

engine = create_engine(DATABASE_URL)
Base = declarative_base()

Сама ошибка:
DB_PASSWORD = test123
