[BUG] MapsSearchClient.getReverseGeocoding() always returns null for MapsSearchAddressCountryRegion.getIso()

[lschuer]

Describe the bug
When requesting an address via the method getReverseGeocoding of the MapsSearchClient, the iso value of the country region is always null.

The reason seems to be a wrong field matcher in the MapsSearchAddressCountryRegion.fromJson() method. The response field is named "iso" but the matcher checks for "ISO".

To Reproduce
Steps to reproduce the behavior: (Kotlin)

val result = mapSearchClient.getReverseGeocoding(
    GeoPosition(-122.138681, 47.630358),
    listOf(ReverseGeocodingResultTypeEnum.ADDRESS, ReverseGeocodingResultTypeEnum.COUNTRY_REGION),
    "Auto"
)

val iso = result.features.firstOrNull()?.properties?.address?.countryRegion?.iso

Expected behavior
I'd expect the value to be filled by the iso code.

Thanks for filing this issue @lschuer

@dubiety could you look into this? ISO appears to be defined in the Swagger https://github.com/Azure/azure-rest-api-specs/blob/main/specification/maps/data-plane/Search/stable/2023-06-01/search.json#L1029

Hi @lschuer ,

You're right. This is a bug from our side. We'll fix it in our next release. Since the API document should be updated as well, this can take some time. I'll notify you once this is updated and released.
