> Happy New Year! 新年快乐！ > > I've investigated further and found the issue with "Export to PDF" & "Download image" not working on dashboards. The issue seems to be the interaction of the headless browser and `WEBDRIVER_BASEURL`. In the docker compose setup `superset_config.py` suggests setting `WEBDRIVER_BASEURL=http://superset_app:8088/`, so accessing the superset instance directly and skipping the nginx reverse proxy. This is fine when there is no url prefix set as the paths that both the reverse proxy and the superset app see are the same. When there is a url prefix set it is baked into the javascript files that webpack builds and when accessing the superset app directly the extra prefix part of the path raises an error in the superset app and the screenshot generation fails.我已经进一步调查并发现“导出为 PDF”和“下载图片”在仪表板上无法工作的问题。问题似乎是 headless 浏览器和 `WEBDRIVER_BASEURL` 之间的交互。在 docker compose 设置中， `superset_con fig.py` 建议设置 `WEBDRIVER_BASEURL=http://superset_app:8088/` ，因此直接访问 superset 实例并跳过 nginx 反向代理。如果没有设置 URL 前缀，这是可以的，因为反向代理和 superset 应用看到的路径是相同的。当设置了 URL 前缀时，它会被烘焙到 webpack 构建的 javascript 文件中，并且当直接访问 superset 应用时，路径的额外前缀部分会在 superset 应用中引发错误，截图生成失败。 > > A fix/workaround (??) seems to be to set `WEBDRIVER_BASEURL = f"http://superset_nginx{base_path}/"` but this also requires removing this [with statement](https://github.com/apache/superset/blob/109e6c69ff25b82b603a4daff40207250788e6b1/superset/utils/urls.py#L35) that seems to set a test context that doesn't know about the prefix. I'm not sure of the knock on effects of this. @rusackas Would you know someone who could comment on this or possibly suggest an alternative approach?一个修复/解决方案似乎是设置 `WEBDRIVER_BASEURL = f"http://superset_nginx{base_path}/"` ，但这也需要删除这个 with 语句，该语句似乎设置了一个不知道前缀的测试上下文。我不确定这会有什么副作用。您认识可以对此发表评论或可能提出替代方法的人吗？ @martyngigg try APPLICATION_ROOT, by setting it to perfix, i found it works -- This is an automated message from the Apache Git Service.
