и снова flask не видит модуль Blueprint'а

  app
    auth
      controllers.py
    main
      controllers.py
__init__.py

import os
from flask import Flask
from .db import db

def create_app():
	app = Flask(__name__)
	app.config.from_object(os.environ['APP_SETTINGS'])

	db.init_app(app)
	with app.test_request_context():
		db.create_all()

	import app.auth.controllers as auth
	import app.main.controllers as main

	app.register_blueprint(auth.module)
	app.register_blueprint(main.module)

	return app

from flask import (
	Blueprint,
	render_template,
	request,
	# flash,
	abort,
	redirect,
	url_for,
	current_app,
	session
)
from sqlalchemy.exc import SQLAlchemyError

module = Blueprint('тут название модуля, либо main, либо auth', __name__, url_prefix ='/')


def log_error(*args, **kwargs):
	current_app.logger.error(*args, **kwargs)


@module.route('/', methods=['GET'])
