Redigo: wrong arguments for XADD

I like Redis streams because Redis becomes aka IoT database with it. Main Redis command for adding something to stream is XADD:

XADD log * name Some_name_to_write text Some_text_to_write

It works fine.

Then I try to use Redigo to do the same operation:

type LogEntry struct {
    Name string `json:"name"`
    Text string `json:"text"`
}

func (l *LogEntry) Push() error {
    var args []string // XADD arguments

    log.Printf("Log Entry: %+v\n", l)
    args = make([]string, 6)
    args = append(args, "log") // Stream key
    args = append(args, "*")   // Auto-generated stream ID
    args = append(args, "name", l.Name)
    args = append(args, "text", l.Text)
    log.Printf("Args for XADD: %+v\n", args)

    new := make([]any, len(args))
    for index, value := range args {
        new[index] = value
    }

    _, err := connection.Do("XADD", new...)
    if err != nil {
        log.Println("XADD error", err)
        return err
    }

    return nil
}

connection here is redis.Conn.

This code produces the following output:

2025-04-08 16:03:08 2025/04/08 13:03:08 Log Entry: &{Name:Some_name_to_write Text:Some_text_to_write}
2025-04-08 16:03:08 2025/04/08 13:03:08 Args for XADD: [      log * name Some_name_to_write text Some_text_to_write]
2025-04-08 16:03:08 2025/04/08 13:03:08 XADD error ERR Invalid stream ID specified as stream command argument

So, I see that arguments for conn.Do exactly the same I use before in CLI.

What's wrong here?

Problem lies here

args = make([]string, 6)

You are creating a slice of string with length 6 but when you call append on it, it adds new item to the slice. Meaning your slice is now has length of 12 not 6. (It has 6 empty strings at the beginning instead of redis commands).

So either just call make with 0 (or just delete the line it will do the same since variable has been declared beforehand)

args = make([]string, 0)
