      "text": "- **An argument is missing, or there's one too many.** Compare your command with the syntax on its command page, such as [`GET`](https://redis.io/docs/latest/commands/get).\n- **Your code passed an empty list.** Commands such as [`DEL`](https://redis.io/docs/latest/commands/del), [`MGET`](https://redis.io/docs/latest/commands/mget), and [`HSET`](https://redis.io/docs/latest/commands/hset) need at least one key or field. When your code builds the arguments from a list that turns out to be empty, the command gets no keys at all. Check for an empty list before you send the command.\n- **A value with spaces was split into several arguments.** In `redis-cli`, `GET my key` sends two arguments, `my` and `key`. Put quotes around a value that contains spaces: `GET \"my key\"`.\n- **The command is `auth`, and you passed a username and a password.** Servers older than Redis 6 accept only a password. Upgrade the server, or send the password alone."
