Getting CORS preflight error even with flask cors initialized

Hey guys, I’ve been trying to get flask_cors to work for over two weeks now, so thought that I would write an issue.

Here’s what is in the init.py file

app = Flask(__name__, static_url_path='/static')
app.config.from_pyfile('config.py')

cors = CORS(resources={
    r'/*': {
        'origins': [
            'http://localhost:8080'
        ]
    }
})

cors.init_app(app)

The error that I’m getting is:

login?redirectNotebook=rose.intro:1 Access to XMLHttpRequest at 'http://localhost:5000/users' from origin 'http://localhost:8080' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status.

Went into the library to poke around and it looks like the after request isn’t being called. The backend is running on localhost:5000 and the frontend is running on localhost:8080, any help would be greatly appreciated!

@Elynad what I did is

from flask import Response

@current_app.before_request
def basic_authentication():
    if request.method.lower() == 'options':
        return Response()

I gave up a long time ago and used a different lib, appreciate it though.
