My DXA JAVA 1.4 website throws these warnings and errors in the log.
16:10:41.157 [http-apr-8080-exec-7] WARN c.s.w.c.impl.DefaultRegionBuilder - Could not find a model type for region Main with MvcData MvcDataImpl(controllerAreaName=Core, controllerName=Region, actionName=Region, areaName=Core, viewName=Navigation, regionAreaName=null, regionName=null, routeValues={}, metadata={})
16:10:41.157 [http-apr-8080-exec-7] ERROR c.s.w.c.impl.DefaultRegionBuilder - Could not find a model type for region Main even using a predefined region
What could cause this? The page works, and the entities in the Main region are shown.
