'where' parameter is invalid on query on feature layer

PeterHudson

Hi everyone,
it has been a week that I have this problem.
I haven't changed anything on my code but 1 week ago I received a "'where' parameter is invalid" error when this query is executed on a feature service (hosted on Arcgis online):

var statDef = new StatisticDefinition();
  statDef.statisticType = "sum";
  statDef.onStatisticField = "Area";
  statDef.outStatisticFieldName = "Tot Area";
  
  var query = new Query();
  query.returnGeometry = false;
  query.where = "Area>0";
  query.outFields = ["Area"];
  query.outStatistics = [ statDef ];
  query.groupByFieldsForStatistics = ["YearEstabl", "TypeName"];
  query.orderByFields = ["YearEstabl", "TypeName"];
  
  var qt = new QueryTask("http://services1.arcgis.com/Mpa25zPNMAT08GQg/ArcGIS/rest/services/AllPropertiesEstablished/FeatureServer/0");
  qt.execute(query, function(result){
                   ...
  }
  });

I am referencing to //js.arcgis.com/3.6/

Any ideas?

Thanks in advance!

You can try by accessing the mapservice as MapServer instead of FeatureServer.....
