ArcGIS API for Python : Error while publishing content

AmritaJayakumar — Fri, 21 Jul 2023 05:24:00 GMT

Dear Team,

I am trying to implement the ArcGIS API for python where in the code im trying to connect to a developer account using an API key, ready a csv file, import into a dataframe and then upload the content as a feature layer.

I have written the code as said in the tutorial. However, it returns an error "'NoneType' object is not subscriptable" at the line csv_item = contentManager.add(csv_properties) as per my understanding.

Please find below the code snippet: (Portion that errs out is highlighted in yellow)

def upload_csv(request): try: csv_filename = request.GET.get("csv_filename","") ARC_GIS_API_KEY = apps.get_app_config('arcgis_bridge').ARC_GIS_API_KEY if csv_filename: if ARC_GIS_API_KEY: gis = GIS(api_key=ARC_GIS_API_KEY) if gis: dir_path = os.path.dirname(os.path.realpath(__file__)) print("dir_path :: ", dir_path) data_path = os.path.join(dir_path, "..\input_data") print("data_path :: ", data_path) csv_path = os.path.join(data_path, csv_filename) print("csv_path :: ", csv_path) ports_df = pandas.read_csv(csv_path) # print("ports_df :: ", ports_df) ports_fc = gis.content.import_data(ports_df) print("ports_fc :: ", ports_fc) # ports_fc_dict = dict(ports_fc.properties) ports_fc_dict = dict(ports_fc.layer) # print("ports_fc_dict :: ", ports_fc_dict) ports_json = json.dumps({"featureCollection": {"layers": [ports_fc_dict]}}) # print("ports_json :: ", ports_json) csv_properties = { 'title': 'test file', 'description': 'attempting content upload from API', 'tags': 'arcgis, python, testing, csv, importing', 'text': ports_json, 'type': 'Feature Collection' } try: contentManager = gis.content print("contentManager :: ", contentManager) csv_item = contentManager.add(csv_properties) print("csv_item :: ", csv_item) csv_item_publish = csv_item.publish() print("csv_item_publish :: ", csv_item_publish) except Exception as e: print("csv_item ERROR :: ", str(e)) return JsonResponse({"error": True, "message":str(e)}) return JsonResponse({"error": False, "message":"CSV Uploaded Successfully.","csv_item_publish":csv_item_publish}) else: return JsonResponse({"error": True, "message":"ARC GIS API CONNECTION COULD NOT BE OBTAINED.","csv_item_publish":{}}) else: return JsonResponse({"error": True, "message":"ARC GIS API KEY IS MISSING.","csv_item_publish":{}}) else: return JsonResponse({"error": True, "message":"CSV FILE NAME IS MISSING.","csv_item_publish":{}}) except Exception as e: return JsonResponse({"error": True, "message":str(e), "csv_item_publish":''})

Terminal Output:

[21/Jul/2023 10:07:50] "GET /arcgis_bridge/uploadCSV?csv_filename=file1.CSV HTTP/1.1" 200 68 dir_path :: C:\Users\aksha\Projects\arc_gis\sree_app\arcgis_bridge data_path :: C:\Users\aksha\Projects\arc_gis\sree_app\arcgis_bridge\..\input_data csv_path :: C:\Users\aksha\Projects\arc_gis\sree_app\arcgis_bridge\..\input_data\file1.CSV ports_fc :: <FeatureCollection> contentManager :: <arcgis.gis.ContentManager object at 0x0000023BC9E03070> csv_item ERROR :: 'NoneType' object is not subscriptable

Looking forward to any support on this regard.

It means that your return from the content.add(...) is None.

contentManager.add(csv_properties)

Something is not set correctly and it's not adding so when it gets to the print, it cant subscript None to str.
