err = r.client.ZAddArgs(context.Background(), base.LeaseKey(qname), redis.ZAddArgs{XX: true, GT: true, Members: zs}).Err()

Redis version >= 6.2.0: Added the GT and LT options.

I encounter the error when using the redis that it's version low than 6.2.0.

@lvsoso Thank you for creating this issue!

I missed the supported redis version when I was browsing the zadd documentation. Since GT is not strictly needed (although it'd be nice if we can add it to convey the intention to "extend" the lease), I'll remove that option for now. XX option should be sufficient in our case, since we check the expired lease before sending the ZADD command to redis.
