I am trying to update a shp file in Arconline with new data. I am trying to replace the data which is the same and add new data that may have been added. I am using truncate and " update "in the ESRI AGOL writer to make sure this happens. But I run into this error when running this
"ArcGIS Online Feature Service Writer: Encountered a feature for feature type 'WatercourseLink_Clip_test' that is missing the ID attribute 'OBJECTID'. This attribute is required
ARCGISONLINEFEATURES writer: A fatal error has occurred. Check the logfile above for details
Clipper_INSIDE_-1_17_Player (RecorderFactory): ARCGISONLINEFEATURES writer: A fatal error has occurred. Check the logfile above for details"
But as far as I can tell both the source data which is being uploaded to update the exisiting data and the exisiting data in AGOL both already have ObjectID's. Any help would be greatly appreciated as I think im missing something quite simple here
