not sure I'll be able to help, I barely use python and never used flask, but the error is referring to something going on in __init__.py inside the website folder can you paste the contents of that in a code block instead of a screenshot? They're much easier to work with

from website import create_app

app = create_app()

if __name__ == '__main__':
    app.run(debug=True)

from website import create_app

app = create_app()

if __name__ == '__main__':
    app.run(debug=True)

from flask import Flask

def create_app():
    app = Flask(__name__)
    app.config['SECRET_KEY'] = 'idk'

    from .views import views
    from .auth import auth

    app.register_blueprint(views, url_prefix = '/')
    app.register_blueprint(auth, url_prefix = '/')

    return app

from flask import Flask

    app = Flask(__name__)

    from .views import views
    from .auth import auth

    app.register_blueprint(views, url_prefix = '/')
    app.register_blueprint(auth, url_prefix = '/')

    return app

and the contents of views.py? can you paste the contents of your views.py

rishitOP•2y ago

from flask import Blueprint

views = Blueprint('views', __name__)

@views.route('/')
def home():
    return "<h1>Test</h1>"

from flask import Blueprint

views = Blueprint('views', __name__)

@views.route('/')
def home():
    return "<h1>Test</h1>"

can you try removing the second register_blueprint line?

    app.register_blueprint(auth, url_prefix = '/')

    app.register_blueprint(auth, url_prefix = '/')

this one

tysm it worked

Jochem•2y ago

you probably have to have unique url_prefix values, maybe that's a new feature in the most recent version of flask or something... if this works, it'll probably also work to change the prefix for the auth one to '/auth/' if it doesn't, I noticed one of the comments on that youtube video said they had to remove the contents of url_prefix, so maybe using url_prefix = '' for views might help too
