I have a class, geolocAddress, that I created to deserialize some JSON using JSON2Apex. I really only need to access the variables from one inner class, Components, but when I try to retrieve the variables from that class, they all have a null value.
Here is the code I'm using to retrieve the variables:
query = q.Job_Site_Geolocation__latitude__s + ',' + q.Job_Site_Geolocation__longitude__s;
System.debug('Query text: ' + query);
req.setEndpoint('https://opencage-geocoder.p.rapidapi.com/geocode/v1/json?language=en&key=[API KEY]&q='+ query);
HttpResponse res = h.send(req);
System.debug(res.getBody());
String jsonBody = res.getBody();
geolocAddress g = (geolocAddress)JSON.deserialize(jsonBody, geolocAddress.class);
System.debug('compList: ' + g.cls_results[0].components);
q.Job_Site_City__c =g.cls_results[0].components.locality;
System.debug('q.Job_Site_City__c = ' + q.Job_Site_City__c);
q.Job_Site_Country__c = g.cls_results[0].components.country;
System.debug('q.Job_Site_Country__c = ' + q.Job_Site_City__c);
q.Job_Site_Postal_Zip__c = g.cls_results[0].components.postcode;
System.debug('q.Job_Site_Postal_Zip__c = ' + q.Job_Site_City__c);
q.Job_Site_State_Province__c = g.cls_results[0].components.state;
System.debug('q.Job_Site_State_Province__c = ' + q.Job_Site_City__c);
q.Job_Site_Street__c = g.cls_results[0].components.house_number + ' ' + g.cls_components[0].road;
System.debug('q.Job_Site_Street__c = ' + q.Job_Site_City__c);
q.Job_Site_County__c = g.cls_results[0].components.county;
System.debug('q.Job_Site_County__c = ' + q.Job_Site_County__c);
Here is the classs created by AdminBooster to deserialize the JSON:

}
This is the JSON that is being returned. (I've confirmed that the JSON is being retrieved, so something is happening either in the deserialization or the way I'm calling the inner class variables for Components.)

What do I need to change in the initial code block in order to retrieve values for the variables in the Components inner class?
replace('"_type"','"x_type"')on the json body before you deserialize and dispense with jsonParser altogether? – cropredy Jul 16 at 15:30
