False Assumption on Redis's `dcode_response`

[AustinJiangH]

This line assumes that the output for keys() are bytes. This assumption is only true when the Redis client is created with decode_responses=False. In the case of True, the return will be a str and it will have error decoding the byte.

langgraph-redis/langgraph/checkpoint/redis/base.py

Lines 405 to 410 in 4ea899f

	matching_keys: List[bytes] = self._redis.keys(pattern=writes_key) # type: ignore[assignment]
	parsed_keys = [
	BaseRedisSaver._parse_redis_checkpoint_writes_key(key.decode())
	for key in matching_keys
	]

It is easy to reproduce as long as you create a Redis client with decode_response=True.
