One of the most annoying bugs to deal with is the ones that happen in production but refuse to show up during local testing. I’ve been wrestling with such a bug all evening. What seemed like a simple fix has turned into a time sink.

The issue centers around a POST request designed to add or edit a MongoDB database record. On my local machine, everything works fine. However, once the code is deployed to production, the request hangs indefinitely and eventually times out. There’s no clear error message or indication of what’s going wrong, which makes troubleshooting all the more challenging.

I have a hunch that the solution will be straightforward — perhaps a minor configuration tweak. Yet, pinpointing the exact cause is proving to be quite the ordeal. It’s moments like these that really test a developer’s patience.
