我正在尝试再次运行e2e量角器测试Selenium Grid-Firefox，但是由于“浏览上下文已被丢弃”，因此继续遇到此错误。
堆栈跟踪的示例是：

奇怪的是，如果我更改测试代码的一部分，它将通过。这是测试样本
import Base from "../../common-pages/base.po";
describe('Edit Page', function () {
let pageName = "AutoQA Page " + base.now();
beforeAll(function (done) {
login = new Login();
login.login(login.userAdmin, login.password);
pages = new Pages();
let newPage = {
'pageName': pageName,
'pageKey': pageKey
};
pages.sendApiRequest('POST', pages.pagesEndpoint, newPage, 200);
done();
});
beforeEach(function (done) {
pages.goto(pages.url);
pages.searchPages(pageName);
pages.getFirstRecordInTable().click(); // this seems to be where context is discarded
form = new PageForm();
appliedPageType = form.getElementText(form.pageTypeField);
done();
});
it('test case #Smoke', function (done) {
// removed test code because it doesn't make it here
done();
});
});
上面的代码不起作用，但是如果我仅将pages.searchPages(pageName);位更改为页面上的某些现有数据（如pages.searchPages("Existing Page A");），它将按预期到达测试代码...
任何帮助将不胜感激。已经尝试了诸如将geckoversion强制为20.0的操作（我已经在s / o上看到了此问题，但没有用）
以下是与我相关的版本：
硒：3.141.59
壁虎驱动程序：v0.24.0
量角器：5.4.1
节点：8.11.4
