`Wrong number of response items from pipeline execution` error on pipeline when client-side-caching is enabled

[iRhonin]

Version: redis-py==5.2.0 redis==7.4.1

Platform: Python==3.8.18 Ubuntu==24.04

Description:

I am getting Wrong number of response items from pipeline execution error when client-side-caching is enabled. The error occurs when using pipeline and at least one of the keys in the pipeline is cached in client.

Steps to reproduce:

r = Redis(protocol=3, cache_config=CacheConfig())

pipe = r.pipeline()
pipe.set('foo', 5)
pipe.set('bar', 18.5)
pipe.execute()

r.get('foo')

pipe = r.pipeline()
pipe.set('foo', 5)
pipe.set('bar', 18.5)
pipe.execute()

Error:

ResponseError                             Traceback (most recent call last)
Cell In[43], line 4
      2 pipe.set('foo', 5)
      3 pipe.set('bar', 18.5)
----> 4 pipe.execute()
