I have a function running Python 3.12 which suddenly started dumping errors (as of today; it worked yesterday). I hadn't changed any code so I found this odd, but after looking through the error logs, it looks like the issue is a missing C++ library 'libstdc++.so.6' which is required by a library I'm using. My guess is something changed on the Appwrite side of things.

So I need some direction on how to work around this... I've tried downgrading from Python 3.12 to Python 3.9, and creating an entirely new function, but neither changed anything and I don't know whether there's something I can do or if this is entirely on Appwrite's side to fix.

Summary

Developer is experiencing errors in Python function due to missing C++ library 'libstdc++.so.6' required by a library being used. Downgrading Python and creating a new function did not resolve the issue. It might be related to changes on the Appwrite side. Possible workaround could be manually installing the missing library in the required path.

Here's the full error log for context:
