I am attempting to use ArcGIS API for Python to overwrite the underlying data of a hosted feature layer with an shapefile. As this layer is used within a Web App and has pre-configured filters, it cannot simply be replaced with a new layer.

Workflow

1) Published the service

 

 

# publish shapefile as feature service
gis = GIS("https://anonymous/arcgis/")
zip_path = '\\\\<anonymise>\\GDW_Catalogue_Items_OS.zip'
published_item = gis.content.add(
    item_properties = {
        "type": "Shapefile", 
        "title": parent,
        "description": "printed maps and charts",
        "tags": "GDW, Catalogue, Footprints, Printed Maps, Printed Charts",
        },
    data = zip_path,
    overwrite=True
)
published_layer = published_item.publish()

# share published feature layer with groups
published_layer.share(groups=['3214a47ac81e4c839a044edf7c42e5ab', '3b3f17e9f2b84aeda789e337da033a7f', 'b4856c293ab84eb389ab323979bd253d', '404b73b5e78b49a0863f8a8cb0f1b6ce'])

 

 

 

2) Sometime later, I wanted to update the data using a new Shapefile:

 

 

# Access hosted feature layer
gis = GIS("https://anonymous/arcgis/")
search_results = gis.content.search('title:GDW_Catalogue_Items_OS AND type:Feature Service')   
feature_layer_item = search_results[0]

# feature collection
from arcgis.features import FeatureLayerCollection
feature_layer_collection = FeatureLayerCollection.fromitem(feature_layer_item)

# call the overwrite() method to update data
zip_path = '\\\\<anonymise>\\GDW_Catalogue_Items_OS.zip'
feature_layer_collection.manager.overwrite(zip_path)

 

 

 

I am given the following error:

 

 

---------------------------------------------------------------------------
Exception                                 Traceback (most recent call last)

Troubleshooting Steps:

  1. Manually updated hosted feature layer using portal (Update Data > Overwrite Entire Layer) - ERROR: 'There was an Error". No more information given.
  2. Manually created a new feature layer on Portal and manually updated using my new shapefile - successful. But does this not work for Step #1?
  3. Ensured my role has the necessary permissions
  4. Ensured 'enable editing' in Settings was ticked
  5. Ensured 'enable sync' was unticked
  6. Ensured both shapefile names were identical
  7. Ensured both shapefile schemas were identical

Please would someone help 🙂
