StructuredMessage not sending response

[bryan-rojas-liquor]

Hi, I'm looping my data into an array_list then I set the StructuredMessage but it doesn't send the response to my FB Messenger Bot.
I logged the array_list (each one is a MessageElement) and this is the output for each element result:

    [18] => pimax\Messages\MessageElement Object
        (
            [title:protected] => Dutch Negroni
            [image_url:protected] => http://mydomain.com/dutch-negroni1.jpg
            [subtitle:protected] => 
            [buttons:protected] => Array
                (
                    [0] => pimax\Messages\MessageButton Object
                        (
                            [type:protected] => web_url
                            [title:protected] => Readmore
                            [url:protected] => http://mydomain.com/dutch-negroni-2/
                        )
            )

    )

I'd like you feedback to solve this or how can it debug this?
Thanks

Do you mean the response from Facebook?

{
  "recipient_id": "1008372609250235",
  "message_id": "mid.1456970487936:c34767dfe57ee6e339"
}
