RuntimeError: Working outside of request context. with gunicorn

Whenever I run my code as python3 myapp.py it works fine but whenever I use gunicorn -w 4 myapp:index -b 10.91.1.230:5055 &

it throws 

ion@aurora:~/TNQ$ [2019-02-05 14:26:34 +0530] [27107] [INFO] Starting

RuntimeError: Working outside of request context.

This typically means that you attempted to use functionality that needed
an active HTTP request.  Consult the documentation on testing for
information about how to avoid this problem.

myapp.py

from flask import Flask,request
from CXE.src.models import class_classic as cc   
app = Flask(__name__)    
@app.route('/', methods=['POST'])
#def index(environ, start_response):
def index(environ, start_response):
    with app.app_context():
        #if request.method == 'POST':
        f = request.files['file']
        a = cc.initiate(f)
    return a   
 if __name__ == '__main__':
    app.run(host = '0.0.0.0',port=5505,debug=True)

I need to put the code on gunicorn for serving it on threads. Any idea why isn't it working ?

It doesn't work because index is not a wsgi app - it's not enough for the function to have the correct signature. Do the following instead:

gunicorn -w 4 myapp:app -b 10.91.1.230:5055 &

You see no issue when you run python3 myapp.py because flask's dev server, app.run, does not require a wsgi app, whereas gunicorn does. With that said, you might as well go ahead and remove the index signature.
