Editing Newsletter Caption (ImageMessage) returns 479

[mircoianese]

Hello,

I'm trying to edit the message caption of an ImageMessage sent on a newsletter.
I have followed the code from this issue, but the edit is returning the following error: "server returned error 479".

This is my code:

data, err := os.ReadFile("./test.jpg")

uploaded, err := client.UploadNewsletter(context.Background(), data, whatsmeow.MediaImage)
if err != nil {
   fmt.Println("Failed to upload file", err)
   return
}

message := &waE2E.Message{
    ImageMessage: &waE2E.ImageMessage{
	Caption:    proto.String("Hello"),
	Mimetype:   proto.String("image/jpg"),
	URL:        &uploaded.URL,
	DirectPath: &uploaded.DirectPath,
	MediaKey:   uploaded.MediaKey,
	//FileEncSHA256: uploaded.FileEncSHA256,
	FileSHA256:    uploaded.FileSHA256,
	FileLength:    &uploaded.FileLength,
    },
}

sendRes, err := client.SendMessage(context.Background(), newsletter.ID, message)
if err != nil {
        fmt.Println("SendMessage failed", err)
	return
}

// The message has been successfully sent

editedMessage := &waE2E.Message{
    ImageMessage: &waE2E.ImageMessage{
	Caption: proto.String("Edit Test"), // edit only the caption
    },
}

res, err := client.SendMessage(context.Background(), newsletter.ID, client.BuildEdit(newsletter.ID, sendRes.ID, editedMessage))

// here "err" contains the 479 error

Any advice?
Thank you

Same problem.....

Then it must be a bug in the library. On other libraries I'm not having the issue

For newsletter, you need to pass the handle in your send message here is fixed code

res, err := client.SendMessage(context.Background(), newsletter.ID, client.BuildEdit(newsletter.ID, sendRes.ID, editedMessage), whatsmeow.SendRequestExtra{
		MediaHandle: `json:"handle"`,
	})
