Hi All,

I'm trying  to complete a challenge related to Apex Rest, but i'm facing a problem when validating it, it's kind of facing an error in the method definition even if i've checked it, below is a snippet of the code and the error message i get from the trailhead : 
 

public class AnimalLocator {
    public static JSON2Apex animalWrapper;
    
    public static String getAnimalNameById(Integer animalId){
        
        Http http = new Http();
        HttpRequest request = new HttpRequest();
        request.setEndpoint('https://th-apex-http-callout.herokuapp.com/animals/'+animalId+':Id');
        request.setMethod('GET');
        System.debug('###request : '+request);
        HttpResponse response = http.send(request);
         System.debug('###response : '+response.getBody() );
        // If the request is successful, parse the JSON response.
        if (response.getStatusCode() == 200) {
            // Deserializes the JSON string into collections of primitive data types.
            animalWrapper  = new JSON2Apex();
            System.debug('Received 1:'+(JSON2Apex)System.JSON.deserializeStrict(response.getBody(), JSON2Apex.Class));
            animalWrapper = (JSON2Apex)System.JSON.deserializeStrict(response.getBody(), JSON2Apex.class);
            
            System.debug('Received the following animals:'+animalWrapper);
            System.debug('###myAnimal : '+animalWrapper.animal.name);
           // return animalWrapper.animal.name;
           
        }
        return animalWrapper.animal.name;
    }  
}

Challenge Not yet complete... here's what's wrong: 
Executing the 'getAnimalNameById' method on 'AnimalLocator' failed. Make sure the method exists with the name 'getAnimalNameById', is public and static, accepts an Integer and returns a String.
