I need some clarification regards log. I had delete some entities from thingworx long ago but its still shown error in script error logs.Please let me know why its shows like that.
The possible reasons are not match with ours. The entities are no where appear in Thingworx and i'm using 8.4 version of thingworx.
Sorry that the article is confusing. Fix for this issue is not yet out for any version of ThingWorx. It just says that it will be fixed for one of the minor versions of those mentioned TWX versions in the future.
Meanwhile, you could also ensure that none of your existing Things' service/subscription code is referring the services/properties of the deleted Things.
