Why This Fix Works in Production

Trigger: poetry run python playground/bug/main.py
Mechanism: Fixes the issue where passing 0.0 longitude or latitude to the geosearch command resulted in an error.
Why the fix works: Fixes the issue where passing 0.0 longitude or latitude to the geosearch command resulted in an error. (first fixed release: 7.1.0).

Production impact:

If left unfixed, the same config can fail only in production (env differences), causing startup failures or partial feature outages.

Why This Breaks in Prod

Shows up under Python 3.9.15 in real deployments (not just unit tests).
Surfaces as: poetry run python playground/bug/main.py

Minimal Reproduction

repro.py

def main():
    redis = Redis.from_url(url="redis://localhost:6379")
    key = "theindex"
    lon: float = 0.0
    lat: float = 1.0
    redis.geoadd(name=key, values=[lon, lat, "foo"])
    results = redis.geosearch(name=key, longitude=lon, latitude=lat, radius=1, unit="km")
    print(results)

Environment

Python: 3.9.15

What Broke

The application raises a ResponseError when executing the geosearch command with invalid arguments.
