Troubleshooting and help

Hello @marcelo_diefenbach,

From what I see, your current deployment runs on python 3.12. The new, failing, deployment is using python 3.13. If you want to keep the older version, create .python-version file with the following content:

3.12.7

You can read more about it here.

This should fix the issue.
Why does it happen? I’m not sure. It seems that in python3.13, for some reason, pip cannot download a binary for the rust-based package pydantic_core and tries to build it and fails.
