I now have the add data widget deployed but when uploading a CSV I get the following error
ERROR 001508: Request to geocode service failed
I believe this is linked to the format of my CSV file and the header row but not certain. Could anyone assist. CSV file is
1,119 avenue,northampton,NN8 1XX
When you add a CSV file with address attribute (No XY data), the map will try to geocode the data.
You need to configure Portal to Geocode Addresses. You may create a custom geocoder by publishing appropriate address Locator from ArcGIS Desktop.
If you don't have a custom geocoder, you could use Esri World Batch Geocoder. To use Esri World Batch Geocoder, you need to configure Portal with an ArcGIS Online Organizational Account (since it consumes credits).
I have several locators in my geocoding section including ArcGis World Geocoding Server. Separately I've added X and Y coordinates to my file, the CSV file uploads and tells me 1 feature but the map is white rather than a dot on my base map.
