Did you try building this container and checking if it worked with the new dependency?

Did you try building this container and checking if it worked with the new dependency?

I've tried running make docker-prod but I get an error down the line that I did not get the time to troubleshoot

edit: turns out dns resolution was failing for a token required to build the image... Deactivating my vpn enforcing certain dns servers did the trick but I have a new error now when poetry tries to install dependencies...

[Miroito]

I made the docker image build by upgrading the version of poetry. With the previous version I ran into python-poetry/poetry#4210. (fixes #1691)
I have no idea how the current docker image successfully built with this problem existing...

I could run make docker-prod and this solution worked. I still have some doubts because somehow the data persisted through fresh builds even though I removed the images and ran system prune after each... Hopefully this is enough now.

More notes:
I've looked a bit deeper into the api Dockerfile and I don't really understand what this is supposed to accomplish?
