In the docs it says:
" You may add one or more layer items to compose a web map or web scene item. Whenever you perform such an operation, you establish a relationship between the items."
I take this to mean that each web map should have a relationship to any layers that have been added to it.
However it seems that if I try to check a map that has a single feature layer, and a publicly hosted basemap I always get the following error for both dependent_to() and dependent_upon() methods:
Unable to get dependents to: 2f1071ac3228427289a6e03d2b625995 Unable to retrieve item dependents.
When I try
It returns an empty array/list.
What are the limitations of these methods? Do they not work if any of the layers are hosted on a public ArcGIS Server? How about an ArcGIS Server that has security setup?
I tried dependent_to on several feature layers and also received the same error.
