IdentifyTask doesn't return results in ArcGIS Server 10.4

Hello,

I'm experimenting an issue about IdentifyTask in ArcGIS API for JavaScript 3.18, with ArcGIS Server 10.4 and DB Oracle 12c (with SDE ST_GEOMETRY).

Every request I make I'm not able to get results:

{"results":[]}

both when I make the request from my WebApp, and if I fill the form in ArcGIS REST services interface.

The code is simple and in old version (Server 10.2.2, Oracle 12c, ArcGIS JSAPI 3.14 it worked well.

[...]
idTask = new esri.tasks.IdentifyTask(layerUrl);
identifyParams = new esri.tasks.IdentifyParameters();
identifyParams.tolerance = 5;
identifyParams.returnGeometry = true;
identifyParams.layerIds = [0, 1];
identifyParams.layerOption = esri.tasks.IdentifyParameters.LAYER_OPTION_ALL;
identifyParams.width = map.width;
identifyParams.width = map.height;
dojo.connect(map, "onClick", execIdTask);
}

function execIdTask(evt) {
var p = evt.mapPoint;
identifyParams.geometry = p;
identifyParams.mapExtent = map.extent;
idTask.execute(identifyParams, function (r) {
handleClick(r)
});
}

Could it be related to something in DB GRANTS to SDE user?

Or something related to new version of AGServer?

Thanks in advance

Gianni

Gianni,

I don't see where you are specifying the identifyParams.spatialReference in your code. Even though your code worked in older versions you should have identifyParams.spatialReference in newer versions.

If the the layer you are using is a query layer you need to enable the St_Geometry library on Oracle Server.
