I'm using elasticbeanstalk command line interface to deploy the flask app.

You're using app.run in production. Don't use the dev server in production.

mod_wsgi, like any WSGI app server, expects to find an application instance when importing, but you're running the dev server instead.

Guard against running the dev server on import. Depending on your mod_wsgi settings, it may expect the name application instead of app as well.

application = app

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