I will fix one python bug and add a regression test

I will reproduce and fix one clearly defined Python bug in a script, CLI, API client, parser, automation, or data utility.

You will receive:

Root-cause diagnosis

A minimal, focused code patch

One regression test using pytest or the project's existing test framework

The exact verification command and result

Clear notes describing what changed

Please provide a public repository, code archive, or the relevant files, the failing command and complete error output, and the expected behavior.

This Gig covers one bounded bug. It does not include broad rewrites, production deployment, credential handling, live-server access, security testing, or major dependency upgrades. If the issue cannot be reproduced because required information is missing, I will identify exactly what is needed before proceeding.
