Postback Persistent Menu Connection error

[bitcoinvsalts]

I am getting this connection error when I click on the postback call from the persistent menu, here is my menu code:

 setMenu(pageId) {
    this.setPersistentMenu({
      pageId: pageId,
      menu: [
            {
               "locale":"default",
               "composer_input_disabled":false,
               "call_to_actions":[
                  {
                    "title": "ℹ️  Menu",
                    "type": "postback",
                    "payload": "MENU",
                  },
                  {
                    "title": '💬  Contact Us',
                    "type": "web_url",
                    "url": "https://m.me/jsapp",
                  },
               ]
             },
           ]
    }, (err, body) => {
      console.log("MENU " + JSON.stringify(err))
      console.log("MENU " + JSON.stringify(body))
    })
  }

At first it works fine but after a while it keeps sending me this error. Anybody else had this issue?

No error log.
