一、环境：
Excel 版本 1905（内部版本 11629.20246 即点即用）连接到 Office 365 专业增强版
Windows 10 企业版 10.0.16299 内部版本 16299
我一直在尝试使用 Excel 中的自定义函数 API，但它始终无法加载我的清单。我正在使用 Visual Studio 进行开发，并使用它来处理侧加载。
加载项似乎部分加载，因为任务窗格确实打开并加载，但我的自定义函数都没有注册。
我还从https://github.com/OfficeDev/Excel-Custom-Functions-JS运行了示例项目，但加载失败并出现类似错误。
我的管理员已授予我访问加载项商店的权限，认为这可能是问题的一部分，但没有帮助。
我相信有一些 GPO 或设置禁用了自定义函数 API，但我不打算找到有关此类设置的任何文档。我已尽我所能确认我提供的清单有效，但 Excel 仍然声称它无效。
Web项目的基本结构如下：
C:.
│ Home.html
│ packages.config
│ WaveyWeb.csproj
│ WaveyWeb.csproj.user
│ Web.config
│ Web.Debug.config
│ Web.Release.config
│
├───dist
│ functions.html
│ functions.js
│ functions.json
│
└───Properties
AssemblyInfo.cs
我已确认 Web 服务器正在预期位置提供页面。
这是我要加载的清单。Visual Studio 不会抱怨它无效，它正在检查架构。如果我做出任何无效的更改，它确实会抱怨。
