my client returns the message: {"addResults":[{"objectId":-1,"globalId" : null,"success":false,"error":{"code":-2147221398,"description":"Geometry does not have Z Value(s)."}}]}
but if I use the example page of the rest api and fill in my post i get the following message: { "error" : { "code" : 400, "message" : "Unable to complete operation.", "details" : [ "Invalid graphic features", "Invalid parameters" ] } }
