_init__.py", line 42, in create_app
app.register_blueprint(auth.bp)
I have initialized the database and everything made all the html files but it gives me this error!I run the site from the terminal and from pycharm.
this is my init file

import os

from flask import Flask


def create_app(test_config=None):
    """ Application factory function """
    # create and configure the app
    app = Flask(__name__, instance_relative_config=True)
    app.config.from_mapping(
        SECRET_KEY='dev',
        DATABASE=os.path.join(app.instance_path, 'flaskr.sqlite'),
    )

    if test_config is None:
        # load the instance config, if it exists, when not testing
        app.config.from_pyfile('config.py', silent=True)
    else:
        # load the test config if passed in
        app.config.from_mapping(test_config)

    # ensure the instance folder exists
    try:
        os.makedirs(app.instance_path)
    except OSError:
        pass

    # a simple page that says hello
    @app.route('/hello')
    def hello():
        return 'Hello, World! Now We are Introducing Mr. Narendra Singh Parihar.THE BOSS !!'

    from . import db
    db.init_app(app)

    return app
def create_app():
    app = ...
    # existing code omitted

    from . import auth
    app.register_blueprint(auth.bp)

    return app

whats wrong with it?It tells me that the error happens in the init file i have initialised the database and such.
