Composite locators that contain a reference to a locator that was added through a portal connection are not supported for publishing, which includes the ArcGIS World Geocoding Service.
Do one of the following to resolve this issue:
- Open the composite locator's Locator Properties dialog box, remove the participating locators that were added from a portal connection, and save the composite locator properties.
- Make an ArcGIS Server connection to the portal, ArcGIS Enterprise or ArcGIS Online and add the locator from the connection to the composite locator. Then republish the locator.
