dnspython | a powerful DNS toolkit for python | DNS library

response_model is an argument to the view decorator (since it's metadata about the view itself), not to the view function (which takes arguments that are necessary for how to process the view):

This is because of a root CA Let’s Encrypt uses (and Mongo Atals uses Let's Encrypt) has expired on 2020-09-30 - namely the "IdentTrust DST Root CA X3" one.

The fix is to manually install in the Windows certificate store the "ISRG Root X1" and "ISRG Root X2" root certificates, and the "Let’s Encrypt R3" intermediate one - link to their official site - https://letsencrypt.org/certificates/

Copy from the comments: download the .der field from the 1st category, download, double click and follow the wizard to install it.

Adding the suitable env vars solved my problem.

Your application is a worker (Procfile declares types -> worker) so it does respond to HTTP requests.

Change to web and make sure you bind the PORT provided by Heroku.

BTW BOTs can run as workers (without dealing with incoming requests) if they poll the server for messages/updates. This is a viable option too (keep it as worker) but ensure the BOT logs what it does at startup.

Here's the problem:

It looks like there's a bug in dnspython, but the fix doesn't seem to be released on PyPi yet.

The best thing I can advise is to install the version from Github:

pip install -U https://github.com/rthalley/dnspython/archive/master.zip

With it your code will work.

You need to remove the quotation marks in your requirement.txt file along with the @rewrite in the Github link. However, instead of removing the @rewrite, just specify the discord version. Replace your requirements.txt file with the following:

After carefully reading log file, here's what I recommend to do for clean deploy.

While venv is activated and you're in project directory (where manage.py live), do the following:

• Open requirements.txt
• Delete unneeded modules from requirements.txt
• Uninstall unneeded modules with pip uninstall module
• Now run pip freeze requirements.txt
• Deactivate venv
• Then add requirements.txt to source control git add -A
• Commit your changes git commit -m "deleted unneeded modules"
• If you have existed Heroku app, connect to it with heroku git:remote -a myapp, else pass this step
• Deploy, git push heroku master

If you are unsure which modules your project need and I can't determin exactly the project's requirements but if you have basic project, you only need 3 modules which are Django, psycopg2-binary, gunicorn, so do the following for clean deploy:

• Delete venv
• Outside project directory, create new one
• Activate venv
• Install the modules you need, probably Django, psycopg2-binary, gunicorn
• Now run pip freeze requirements.txt
• Deactivate venv
• Then add requirements.txt to source control git add -A
• Commit your changes git commit -m "deleted unneeded modules"
• If you have existed Heroku app, connect to it with heroku git:remote -a myapp, else pass this step
• Deploy, git push heroku master

Searching for the exception, leads to the corresponding eventlet issue: https://github.com/eventlet/eventlet/issues/687

The summary is that eventlet (0.32.0) is currently not compatible with Python 3.10 because it tries to patch types that have become immutable in Python 3.10.

Like with your requirements, it is good practice to be more specific with your Docker dependencies too. Today using the tag 3 for the Python Docker image will give you 3.10.0, unless it is using a cache. In the future it could be a different version. Since there is a compatibility issue with Python 3.10, use Python 3.9 - the currently latest Python 3.9 Docker tag is 3.9.7.

i.e. it should work once you change your first line of the Dockerfile to:
