Zappa deploy error deployed lambda failed. A GET request to '/' yielded a 502 response code

I have zappa setting json (zappa_settings.json) as below:

{
    "dev": {
        "app_function": "manage.app",
        "aws_region": "ap-southeast-1",
        "profile_name": "default",
        "project_name": "digital-agency-ms",
        "runtime": "python3.6",
        "s3_bucket": "lambda.com",
        "use_precompiled_packages": false
    }
}

I run my application in local by the command python manage.py run

here is my manage.py :

"""Manage all command related to the micro-service."""
import unittest
import time
from app import app, manager


@manager.command
def run():
    """Run the app."""
    app.run(host='0.0.0.0')


@app.route('/')
def index():
    return "Hooray, you catch me !", 200


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

when I run zappa deploy dev it returns 502 response error ERROR showing :

Error: Warning! Status check on the deployed lambda failed. A GET request to '/' yielded a 502 response code.

here is zappa log :

what is the option - I am missing?

Fixed this issue by removing the package

  Flask-Bcrypt==0.7.1

from requirements.txt

reinstall packages
