Empty JSON values (LWC)

Question

Hi guys
I'm trying to get some "hardcoded" values from an apex Method, but when I write a console.log it's comming empty.

Here's the code I'm working on:

@wire(getValues)
wiredValues({error, data})
     if(data) {
     console.log("Data::::::",data);
     this.getVal = JSON.stringify(data);
     } else if(error){
           this.error = error;
           this.getVal = undefined;
           console.log("No values");
     }

Here's my apex method(I'm trying to make kind of "fake" callout but i'm not sure if im right):

public without sharing class getSomeValues {
       @AuraEnabled(cacheable = true)
       public static List<wrapVal> getWrapVal() {

        HttpResponse request = new HttpResponse();
        request.setBody('{"Values": ["1000", "2000", "3000", "4000", "5000"]}');
        Map<String, Object> results = (Map<String, Object>) 
        JSON.deserializeUntyped(request.getBody());
        List<Object> sumVal = (List<Object>) results.get('Values');
        List<wrapVal> newLstValues = new List<wrapVal>();

        for (Object getValues : sumVal ) {
             wrapVal newLstValue = new wrapVal();
             newLstValue.nwValue = String.valueOf(getValues);
             newLstValues.add(newLstValue);
             System.debug("getValues::::::"+ newLstValue.nwValue);
       }
        return newLstValues;
  }

  public class wrapVal {
  public String nwValue { get; set; }
  }

Debug:

So idk what i'm doing wrong, if can share with me some advice or documentation it'd be great. Thanks

It seems like you need to decorate the properties of the class wrapVal with @AuraEnabled. Otherwise LWC won't receive them.

 public class wrapVal {
  @AuraEnabled
  public String nwValue { get; set; }
  }
