Option A — Upgrade to fixed release\npip install redis==7.1.0\nWhen NOT to use: Do not apply this fix if the application relies on the previous behavior of ignoring the 'push_request' argument.\n\n

Why This Fix Works in Production

Trigger: self.run()
Mechanism: Fixes the unexpected keyword argument 'push_request' in SentinelManagedConnection.read_response() method.
Why the fix works: Fixes the unexpected keyword argument 'push_request' in SentinelManagedConnection.read_response() method. (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 3.10 in real deployments (not just unit tests).

“The same issue is also valid for the async client: redis.asyncio.client.PubSub.parse_response() is calling redis.asyncio.sentinel.SentinelManagedConnection.read_response() with unexpected push_request argument.”

“Same issue with v5.0.0. The new version seems broken and does not work with Redis Sentinel.”
