Javascript 为什么browser.tabs.query在“边缘扩展”中不工作？

我正在使用下面的函数获取当前选项卡

/**
 * Get the current tab.
 *
 * @param {function(tabObject)} callback - called when the URL of the current tab
 *   is found.
 */
function getCurrentTab(callback) {
// Query filter to be passed to browser.tabs.query - see
// https://developer.browser.com/extensions/tabs#method-query
var queryInfo = {
    active: true,
    currentWindow: true
};
browser.tabs.query(queryInfo, function (tabs) {
    if (browser.runtime.lastError) {
        // Something went wrong
        console.warn("Whoops.. " + browser.runtime.lastError.message);
        // TODO: Show error to the user
        return false;
    } else {


        // browser.tabs.query invokes the callback with a list of tabs that match the
        // query. When the popup is opened, there is certainly a window and at least
        // one tab, so we can safely assume that |tabs| is a non-empty array.
        // A window can only have one active tab at a time, so the array consists of
        // exactly one tab.
        var tab = tabs[0];

        // A tab is a plain object that provides information about the tab.
        // See https://developer.browser.com/extensions/tabs#type-Tab
        callback(tab);
    }
});

}

我收到了这个警告哎呀。。功能不正确

有人能帮我解决这个问题并告诉我我做错了什么吗？

您的代码在Edge 40.15063中正确运行。您在manifest.json中是否具有“tabs”权限？是的，我已在permissionsHow中包括了这两个选项卡以及activeTab关于在那里设置断点的内容，并检查是否定义了选项卡/选项卡[0]？也许您可以忽略错误，或者您的回调无效，或者错误对象中有更多错误。另外，摆弄queryInfo可能有助于检测哪些内容被破坏了。@AnatolySazanov我检查了，选项卡[0]未定义
