Got an error if message size exceeds 128k: the message is illegal, maybe msg body or properties length not matched. msg body length limit 128k, msg properties length limit 32k.

I'm using golang rocketmq-client as producer to send message.
https://github.com/apache/rocketmq-client-go
I tried to send message with SendSync() function.
If message size less than 128k, it works fine.

    // golang code
    msg := &primitive.Message{
        Topic: Cfg.Topic,
        Body:  []byte(message),
    }

    res, err := Producer.SendSync(context.Background(), msg)
    if err != nil {
        return err
    }

If the message size exceeds 128k, I got an error:

the message is illegal, maybe msg body or properties length not matched. msg body length limit 128k, msg properties length limit 32k.

Printing broker config with following command:

mqbroker.cmd -p

...
maxMessageSize=4194304
...

What's the problem please?

Because my message size exceeds 4MB
