/project/ 上的 TypeError 强制转换为 Unicode：需要字符串或缓冲区，找不到 NoneType
TypeError at /project/ coercing to Unicode: need string or buffer, NoneType found
我使用本指南 OSA 全新安装了 OpenStack Ansible。 运行 剧本后，安装成功完成，没有任何失败 plays/tasks。使用 Ubuntu 16.04 服务器部署服务器。
但是，当我转到 OpenStack 仪表板并登录时，我收到此错误 pastebin。

我不明白这个错误。当我使用 OS 客户端时，OpenStack API 工作正常。唯一的问题是由于这个问题我无法使用 OpenStack 仪表板。
请帮忙。提前致谢。
我也遇到了这个问题。我希望我的经验对遇到此问题的其他人有所帮助。就我而言，我只是从仪表板设置的策略过滤器中删除了 'orchestration'。
您可以尝试在设置文件 (/etc/openstack-dashboard/local_settings.py):
中注释掉这一行

例如在/etc/openstack-dashboard/local_settings.py
