Problem accessing feature layer on cloud (arcgis online)

Hi everyone,

I'm using the Access feature data in the cloud sample with my own service from ArcGis online, i have no particular error in my code and my basemap appear in the app. Can't find why my feature layer "monuments" doesn't appear. Any ideas? Thanks!
