Django app build packs error have suddenly disappeared

Hi all!

I’m trying to deploy a Django app to DO, but I’m getting a weird response. Yesterday I deployed the same app and everything was OK, but today I’m not able to do it again (I had to fix a small issue, so I need to deploy iy again). Here you can find the logs I’m getting:

[2023-10-11 10:09:34] ╭──────────── buildpack detection ───────────╼
[2023-10-11 10:09:34] │  › using Ubuntu 22.04 stack

[2023-10-11 10:09:36] │    review the buildpack documentation for more info: https://do.co/apps-buildpacks
[]

I’ve been investigating a bit and I found out that this problem may happen when the repo does not contain a requirements.txt/setup.py/Pipfile, which is not my case. I’ve changed some lines in my python code, but I’ve neither installed any additional package nor changed the requirements.txt file. In addition, I’ve read that DigitalOcean’s default Python version has recently changed, but I think this cannot be the reason as I have a runtime.txt in my repo specifying the version I need (3.11.3). Thus, I can’t understand why the file is not being detected from one day to the next

I’ve also notified that the Python build pack no longer appears in the Build Phase section of my project’s settings.

Any idea of how can I solve this? Thank you so much in advance!
