Why This Fix Works in Production

Trigger: Users could not retrieve raw data from Redis, leading to data compatibility issues.
Mechanism: The async version of `read_response` did not utilize the `disable_decoding` parameter
Why the fix works: Fixes the async `read_response` method to utilize the `disable_decoding` parameter, addressing issue #3035. (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

The async version of `read_response` did not utilize the `disable_decoding` parameter
Production symptom (often without a traceback): Users could not retrieve raw data from Redis, leading to data compatibility issues.

Fix Options (Details)

Option A — Upgrade to fixed release Safe default (recommended)

pip install redis==7.1.0

When NOT to use: Do not use this fix if you require decoding for all responses.

Use when you can deploy the upstream fix. It is usually lower-risk than long-lived workarounds.

Option C — Workaround Temporary workaround

(as in https://github.com/redis/redis-py/issues/1006#issuecomment-1100506453 ), but it's not a very clean solution.

When NOT to use: Do not use this fix if you require decoding for all responses.

Use only if you cannot change versions today. Treat this as a stopgap and remove once upgraded.
