Hi,

You need to add method definition and return type as given in the module.

Please refer below code which is executing.
  
override global DataSource.TableResult query(DataSource.QueryContext queryContext) {
  List<Map<String, Object>> properties = DataSource.QueryUtils.process(queryContext, getProperties());
  DataSource.TableResult tableResult = DataSource.TableResult.get(queryContext, properties);
  return tableResult;
}

public List<Map<String, Object>> getProperties() {
  Http httpProtocol = new Http();
  HttpRequest request = new HttpRequest();
  String url = 'https://ionic2-realty-rest-demo.herokuapp.com/properties/';
  request.setEndPoint(url);
  request.setMethod('GET');
  HttpResponse response = httpProtocol.send(request);

  List<Map<String, Object>> properties = new List<Map<String, Object>>();

  for (Object item : (List<Object>)JSON.deserializeUntyped(response.getBody())) {
    Map<String, Object> property = (Map<String, Object>)item;
    property.put('ExternalId', property.get('id'));
    property.put('DisplayUrl', 'https://ionic2-realty-rest-demo.herokuapp.com/');
    property.put('Name', property.get('title'));
    properties.add(property);
  }

  return properties;
}

Hope this helps you!
