chrome.tabs.getCurrent() or tabs.query()

Both methods are producing the same error Uncaught TypeError: Cannot read property 'query' of undefined for my content script... I've already looked at How to fetch URL of current Tab in my chrome extension using javascript and How do you use chrome.tabs.getCurrent to get the page object in a Chrome extension? though I'm still not sure what I'm doing incorrectly.

manifest.json 

{
  "name": "Extension Tester",
  "version": "0.0.1",
  "manifest_version": 2,
  "description": "Tester",
  "permissions": [
    "tabs"
  ],
  "content_scripts": [
    {
      "matches": ["https://www.google.com/"],
      "js": [
        "inject.js"
      ]
    }
  ]
}

inject.js

chrome.tabs.query({ currentWindow: true, active: true }, function (tabs) {
  console.log(tabs[0].id);
});

or

chrome.tabs.getCurrent(function (tab) {
  console.log(tab.id);
});

Cannot use chrome.tabs in content script,you need to use chrome.runtime To know the tab id of the content script, first use chrome.runtime.sendMessage to send a message, and the background page receive it.

Using chrome.runtime.onMessage.addListener, the callback function is

function(any message, MessageSender sender, function sendResponse) {...};

so, you will know the tab id by sender.id
