I have this that I have made by myself but it doesnt work, i got an error. What am i missing? var qTask = new QueryTask(layers.read_repartos(token)); var q = new Query(); var statisticDefinition = new StatisticDefinition(); statisticDefinition.statisticType = "count"; statisticDefinition.onStatisticField = "created_date"; q.where = "created_user= 'vialactea\czeballo'"; q.outFields=["*"]; q.outStatistics = [statisticDefinition]; qTask.execute(q, (featureSet) => { console.log(featureSet) var us = featureSet.features.map(u=>{ var ob = { key: u.attributes.created_user, text: u.attributes.created_user, value:u.attributes.created_user, content:u.attributes.created_user } return ob; }); return resolve(us); }, (error) => { console.log(error) });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
