unable to load app 0 (mountpoint='') - Flask app with uwsgi

Question

I have a python flask app in below structure

Admin
   |-app
       | -__init__.py
   |-wsgi.py

My wsgi.py contents is as follows

#!/usr/bin/python

from app import app
from app import views


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

Contents of init.py in app package

#!/usr/bin/python

from flask import Flask

app = Flask(__name__)

I started wsgi as below

uwsgi --socket 127.0.0.1:8080 --protocol=http -w wsgi

The server is started successfully but I can error in startup log as below

Similar issues were posted but whatever solutions offered for those issues are already in my code. I am not able to find why I am getting this error.

Thanks

Answer 1

"Callable not found is the issue" (not the import error, i suspect). Change:

uwsgi --socket 127.0.0.1:8080 --protocol=http -w wsgi

into this

uwsgi --socket 127.0.0.1:8080 --protocol=http -w wsgi:app

or

uwsgi --socket 127.0.0.1:8080 --protocol=http --module wsgi --callable app

see here, search for 'flask deploy'.
