I have a Flask app running on top of gunicorn. I set up my run configuration like so:

 

* Enabled Gevent compatible on the python debugger preferences. 

* set the Script in the run config to point to my virtual environment's gunicorn

* set the params as needed

 

It all works fine when I run the script. but when I try to debug I get the following Error from pycharm:

Hello Refael!

 

Could you please: 

1. upload your logs folder zipped from Help | Compress Logs and Show in…

2. provide a code example, so I will be able to reproduce the issue 

 

Please upload the information to the FTP:

https://uploads.services.jetbrains.com/ and let me know the folder name. 

 

 

Thank you!

I uploaded logs to the link you have sent (logs-20191103-130959.zip - not sure where its saved).

I hope this example will reproduce your error:

 

in a python file:

 

import eventlet

eventlet.monkey_patch()

from flask import Flask
app = Flask(__name__)

 

then in run configuration

gunicorn --bind 0.0.0.0:1337 --worker-class eventlet --no-sendfile --timeout 300 -w 1 <path_to_app>:app

 

and try debugging
