浏览器出现后 Nightwatch 立即崩溃 - 正在运行且未进行任何更改

Question

我有一个 Nightwatch 项目运行ning 在每天的计时器上测试我的网站。我有一个日志文件，我每隔几周检查一次，以确保一切顺利。今天我注意到它已经运行ning，但在运行ning 几秒钟后崩溃（通常需要半小时才能完成所有操作）。

过去一周我没有更改代码、更新任何程序包或节点，也没有故意更改计算机上的任何其他内容。

我在我的代码中放置了很多记录调用（我不得不使用我的 fs 记录器，因为 console.log 没有像往常一样在进程运行之后出现）。它并不总是通过代码在同一点退出，所以我认为这是 Nightwatch 的问题而不是我的。

我创建了一个简单的测试文件，可以用来查看我的复杂测试是否搞砸了。它会将日志打印到我的文件中，但不会运行任何测试，并且浏览器弹出不到一秒钟，然后整个系统崩溃。

当前测试:

const fs = require('fs');

module.exports = {
    '@tags': ['getDistricts'],
    'Get Districts Assert Title': function (browser) {
        fs.appendFile("./log.txt", "\nBROWSER: " + JSON.stringify(browser), function (err) { });
        browser.pause(100000); //prevent method from ending before tickets are retrieved
        fs.appendFile("./log.txt", "\nNew run: " + new Date(), function (err) { });
        browser
            .url('https://www.google.com')
            .waitForElementVisible('body')
            .assert.title('Google')
        fs.appendFile("./log.txt", "\nRan tests", function (err) { });
    }
};

我一直无法弄清楚为什么它停止工作，但我从头开始并在最新版本的 Nightwatch 上重建项目并复制我的测试并再次工作。

Nightwatch crashes as soon as browser appears - was working and made no changes
