SP2016 - SP2016 FP2上的Spfx Webpart

Question

我尝试构建一个新的Webpart，目标是SP16 FP2＆amp; SP在线。
https://docs.microsoft.com/en-us/sharepoint/dev/spfx/web-parts/get-started/build-a-hello-world-web-part

当我将软件包部署到我的SP16时，应用程序不会显示在我的其他网站上。

在我的ULS日志中，我只有以下错误：

Unexpected Exception in SPDistributedCachePointerWrapper::InitializeDataCacheFactory for usage 'DistributedClientSideAppUpdateTimeCache' - Exception 'System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.     at System.Collections.Concurrent.ConcurrentDictionary`2.get_Item(TKey key)     at Microsoft.SharePoint.DistributedCaching.SPDistributedCachePointerWrapper.InitializeDataCacheFactory()'.

任何想法我做错了什么？
