Hey @ulyssear, I had also tried this but my github-action always failed:-
https://github.com/Anurag-Nagpal/codethesaur.us/actions/runs/6669393621/job/18127070143

I see your github-action is also failing with the same error, downloading requirements.txt in docker(specifically package psycopg2-binary-2.9.5).

 Error: pg_config executable not found.

I am curious how you will handle this error to pass the github-action, I am now able to figure out how to resolve this.

Hello ! I resolved the issue in this pull request : #665 (comment)

[geekygirlsarah]

I'll tentatively approve this but won't merge until the other PR that changes Dockerfile is merged, and we retest this. Thanks!

I removed Dockerfile of the indexed files in PR #665

The test works but fails because the Docker container needs an update, so I can merge this in (and we hopefully fix this soon).

Thank you!
