TypeError: 'module' object is not callable while deploying flask app using uwsgi/nginx

Question

I am deploying a flask web app using uwsgi and nginx following this tutorial . When I run the command uwsgi --socket 0.0.0.0:5000 --protocol=http -w wsgi:app as mentioned in tutorial for testing, it gives error TypeError: 'module' object is not callable on any api requests or any end points. Although simple running python wsgi.py file on port 5001 , all requests return response without any error.

Code in wsgi.py

from ds_app import factory
import ds_app as app
if  __name__=="__main__":
    app = factory.create_app(celery=app.celery)
    app.run()

Response while running uwsgi command is below.

Can anybody help me why same code giving error while running using uWSGi command. Any leads highly appraciated.

Answer 1

Moving code outside if main worked.

from ds_app import factory
import ds_app as application
app = factory.create_app(celery=application.celery)
if  __name__=="__main__":
    app.run()
