Chrome extension chrome.tabs missing from chrome object?

Question

JavaScript

When executing the script via chrome.tabs.executeScript(). In the chrome object, the script being executed does not have a tabs object, the rights are set in other places, but not here.

chrome.tabs.executeScript(tab[0].id, {
    file: 'popupExecutor.js'
     }, function () {
     console.log('Run script');
});

Answer 1

tabs undefined only in two cases, perhaps: either there are no rights in the manifest, or the call is not from the background page.
