geoserver.log:无法将上下文gwc作为工作区查找，而是作为组进行尝试
我使用了从官方网站下载的Geoserver 2.20，配置了gwc缓存系统，并在全局设置上为缓存和OGC服务启用了层。
当我尝试这个URL时，我得到以下信息：
$ curl 'http://myserver/geoserver/geoserver/gwc/service/wms?SERVICE=WMS&REQUEST=GetMap&BBOX=-180,-90,0,80.33032694475760138&SRS=EPSG:4326&WIDTH=846&HEIGHT=800&LAYERS=ws:mylayer&FORMAT=image/png'

...我已经尝试了另一个网址http://myserver/geoserver/geoserver/ws/gwc/service/wms?SERVICE=WMS&REQUEST=GetMap&BBOX=-180,-90,0,80.33032694475760138&SRS=EPSG:4326&WIDTH=846&HEIGHT=800&LAYERS=ws:mylayer&FORMAT=image/png，不要运行太。
但是，用于同一服务器和层(with)的另一个URL运行ok：http://mysever/geoserver/gwc/demo/ws:mylayer?gridSet=EPSG:4326&format=image/png。
我寻找过这个相关的问题(Geoserver:No such workspace 'gwc/service')，但没有解决我的问题。
我该怎么解决呢？
致以问候。

问题在于URL。这是不正确的。
正确的URL必须引用wmts服务而不是wms。
因此，它应该是(对于这个例子)：
http://myserver/geoserver/geoserver/gwc/service/wmts?SERVICE=WMS&REQUEST=GetMap&BBOX=-180,-90,0,80.33032694475760138&SRS=EPSG:4326&WIDTH=846&HEIGHT=800&LAYERS=ws:mylayer&FORMAT=image/png
可用层：
http://myserver/geoserver/geoserver/gwc/service/wmts?
