No need for getSelected, you should just use chrome.tabs.query correctly:

chrome.tabs.query({currentWindow: true, active: true}, tabs =>  chrome.tabs.sendMessage(tabs[0].id, token));

Getting a new error...

code: 

popup.js:

//background

chrome.runtime.sendMessage({popupOpen: true});

document.addEventListener('DOMContentLoaded', function() {

    document.querySelector('button').addEventListener('click', onclick, false);

    function onclick() {

        var token = document.getElementById("token").value

   

        chrome.tabs.query({currentWindow: true, active: true}, tabs =>  chrome.tabs.sendMessage(tabs[0].id, token));

   

    }

}, false);

It means the content script doesn't run in the tab or there's no onMessage listener. If you reloaded the extension on chrome://extensions page without reload the tab(s), the content scripts won't run by themselves in Chrome, see https://stackoverflow.com/q/10994324
