Deploy failed when migrating from Heroku

My original message in my slack channel, which explains the situation, as follows:
Good afternoon everyone. I am getting the following psycopg errors. I have tried most things under the sun and not able to deploy my project successfully to Heroku. I reached out to Heroku, who gave me the following link, which I also implemented with no success: Heroku article dot com/articles/connecting-heroku-postgres#connecting-in-python the actual problem code that they mentioned was at:

2023-05-04T22:58:07.473453+00:00 app[web.1]: import psycopg2 as Database
2023-05-04T22:58:07.473453+00:00 app[web.1]: File “/app/.heroku/python/lib/python3.11/site-packages/psycopg2/”, line 51, in
2023-05-04T22:58:07.473454+00:00 app[web.1]: from psycopg2._psycopg import ( # noqa
2023-05-04T22:58:07.473454+00:00 app[web.1]: SystemError: initialization of _psycopg raised unreported exception

I’ve also raised an issue with stackoverflow: python - Why does psycopg2 raise a postgreSQL error when deploying Django site to Heroku? - Stack Overflow with a more detailed synopsis of my problem, and currently waiting for a savvy developer to possibly be able to assist, as my tutor hours for this week are done. Any advise would be greatly appreciated. (edited)

Since the above message, I decided to deploy to, as I had problems with a previous heroku deployment, but the same code was able to deploy successfully to Render. I followed the render steps:
render. com/docs/migrate-from-heroku#step-1-generate-a-dockerfilerender-and-renderyaml

and the deployment failed with error codes:

May 5 01:25:14 PM 23 | # in place. We then run the script here because, unlike our
May 5 01:25:14 PM 24 | # v2 image, this allows us to expose build-time env vars to your app.

May 5 01:25:14 PM --------------------
May 5 01:25:14 PM error: failed to solve: process “/bin/bash -c /render/build-scripts/ ${HEROKU_STACK}” did not complete successfully: exit code: 1
May 5 01:25:14 PM error: exit status 1

That thing about theh Procfile, I’m not understanding, as my Procfile is configured, as follows:
web: gunicorn django_newssite.wsgi:application -b

-Any help would be greatly appreciated, thanks.

Hi Eric,

Looking at the errors you got on Heroku I would be looking at your DATABASE_URL to double check it has been configured correctly. This is generally one of the first places to look when psycopg2 is throwing errors.

As for your issues on Render, can I suggest you open a ticket directly with us so we can look more closely into the build errors you are having?
