redisLock 中context 代码错误

源码： func (r Lock) Lock(key string, unixTsToExpireNs int64) error { now := time.Now().UnixNano() expiration := time.Duration(unixTsToExpireNs + 1 - now) ctx := r.rclient.Context()

success, err := r.rclient.SetNX(ctx, key, unixTsToExpireNs, expiration).Result()
if err != nil {
	return err
}

错误信息：

github.com/RichardKnop/machinery/v2/locks/redis

....\pkg\mod\github.com!richard!knop\machinery\[email protected]\locks\redis\redis.go:67:19: r.rclient.Context undefined (type "github.com/redis/go-redis/v9".UniversalClient has no field or method Context)

ctx := r.rclient.Context() 这行代码错误，我使用的是最新版本，没有context 方法
