当 运行 基于 selenium 库的测试用例在 DOCKER 容器内具有无头 chrome 时，Robot Framework 测试用例失败并显示“找不到元素”
Robot Framework test case fails with “Element not found” when running selenium library based test case with headless chrome inside a DOCKER container
下面是我试图在 docker 容器内执行的测试用例。

当我试图在MAC终端中直接从IDE（Pycharm）执行时测试用例成功通过。但是，当我尝试通过 docker 容器执行相同操作时，它失败并出现错误“找不到带有定位器 'id=username' 的元素”，并且在日志中附加了一个空白屏幕作为屏幕截图的一部分。我请求的页面应该被重定向到带有用户名密码字段的身份验证页面（密钥斗篷），但我在 docker 容器中得到空白页面。
我检查了容器“/usr/lib/chromium/chrome_debug.log”中的日志文件

我什至提到了 link Getting empty page running selenium in headless chrome Docker。
我想不出可能是什么问题。这真的是重定向问题或证书问题或混合内容吗？我很困惑。有什么想法吗？
我找到了上述问题陈述的解决方案。
首先我尝试使用 chrome 和 firefox 而不是 chromium。但是 apline 没有 chrome，因此将我的基本图像切换为 ubuntu。此外，一般来说，建议 ubuntu [参考：https://pythonspeed.com/articles/base-image-python-docker-images/] 作为 运行ning Python 的最佳 docker 基础图像申请。
但即使在 chrome 和 firefox 更改为 ubuntu 作为新的 docker 基本图像后，它仍然是相同的错误（空白页面白屏）。
也低于错误，
