We have a 10.9.1 Standalone Server. Published a composite locator created and published from ArcGIS Pro 3.3.1.
The issue we are trying to debug is with /rest/services/Test_Locators/Locatortest/GeocodeServer/geocodeAddresses call when trying to use SingleLine JSON Input.
We cannot search address if the JSON is with "SingleLine": "380 New York St, Redlands, CA 92373" input.
It works if we use "Street": "380 New York St, Redlands, CA 92373" as JSON input, which is not correct as per ESRI docs.

The same Composite Locator works with SingleLine inputs on 11.4 Enterprise Env.
Thanks for any help!
