BUG-000110783 for Collector Classic for ArcGIS (iOS)

Bug ID Number	BUG-000110783
Submitted	January 16, 2018
Last Modified	February 10, 2025
Applies to	Collector Classic for ArcGIS (iOS)
Operating System	Apple iOS
Status	Known Limit

Additional Information

This is a known limitation when publishing from ArcGIS Desktop with non-nullable attribute fields. Text fields contain spaces and numerical fields contain zeros as default values. Collector for ArcGIS reads the default values when creating features. As an additional workaround, use the Reset Required Fields tool in the Collector Utils tools in ArcGIS Pro with hosted feature services from ArcGIS Online or ArcGIS Enterprise. This does not work with ArcGIS Server. This tool removes those spaces and zeros from the non-nullable fields, therefore allowing them to show up as 'required' in Collector for ArcGIS. https://github.com/Esri/collector-tools/blob/master/CollectorUtils/pro/ResetRequiredFields.md https://github.com/Esri/collector-tools

Workaround

Use Collector for ArcGIS. If users are using Collector for ArcGIS Classic, follow the steps below:

After publishing the hosted feature service to ArcGIS Online, navigate to the service's REST.
Insert admin into the REST URL in order to access Admin operations. For example: https://services.arcgis.com/<org id>/arcgis/rest/admin/services/<service name>/FeatureServer/0?token=<token>
Click on the service's layer to navigate to the layer's Admin REST endpoint.
Click Update Definition.
Search for "lastEditDate" : <number> line.
Remove <number> from line and replace it with ''. For example: "lastEditDate" : ''
Search for the field's template and replace the field name's " " value with null value.
Click Update Layer Definition.
Add the newly updated layer into a new web map to consume the map in Collector for ArcGIS Classic, or refresh the existing maps in Collector for ArcGIS Classic. The required fields are honored in Collector for ArcGIS Classic.
