Adding an extra value to a coded value domain of a hosted feature layer published from ArcGIS Pro and has domains and subtypes defined returns the "Domain already exists" error message in the ArcGIS Field Maps app.

Solution de contournement

• Remove the value of the domain that is added after publishing the layer.
• Add the extra value to the domain in ArcGIS Pro and re-publish the layer from ArcGIS Pro.

1. Navigate to the REST API in ArcGIS Online and find the layer to update.
2. Change /rest/services/ in the URL to /rest/admin/services/ and press Enter.
3. Navigate to Update Definition.
4. Make the appropriate changes to the JSON code by updating the domains listed under the subtypes.
5. Click Update Layer Definition.
