You could treat the following click event as a Print Task (PrintTask | API Reference | ArcGIS API for JavaScript 3.18 ) event.  Just submit the current map to the Print Task and grab the resulting image returned from the Print Service.  You could play around with the output extent by adjusting it with the esriRequest.setRequestPreCallback (esri/request | API Reference | ArcGIS API for JavaScript 3.18).  Also use the MAP_ONLY option for the layout. ...

Your first query is performed on a polygon layer (determined from the Map Service description at https://enviroatlas.epa.gov/arcgis/rest/services/National/ESN_CleanAir/MapServer/21).  The input polygon rings intersect with 2 geometries.  Add * to the Out Fields option to get the rest of the record field values like this example and the results for the MeanPrecip field can be used. Your second query with the error is performed on a raster layer.  This is most probably the layer on which the zonal statistics for each parcel was based.  You could do an Identify operation on this layer and look at the resulting "Pixel Value" field, although this will only return the result for a single pixel and not the average (or whatever statistic) for the selected parcel. ...

I think you should start by having a look at the Web_Map_as_JSON object being passed to the server in the Print Task execute request.  The text should be contained by a graphicsLayer object with a text symbol defined, where the text size should be an integer value e.g. { "id":"graphicsLayer5", "opacity":1, "minScale":0, "maxScale":0, "featureCollection":{ "layers":[ { "layerDefinition":{ "name":"textLayer", "geometryType":"esriGeometryPoint" }, "featureSet":{ "geometryType":"esriGeometryPoint", "features":[ { "geometry":{ "x":2549897.66787728, "y":-3885519.2773505934, "spatialReference":{ "wkid":102100 } }, "symbol":{ "color":[ 255, 255, 255, 255 ], "type":"esriTS", "verticalAlignment":"baseline", "horizontalAlignment":"left", "angle":0, "xoffset":3.75, "yoffset":3.75, "text":"graphic-0", "rotated":false, "kerning":true, "font":{ "size":12, "style":"normal", "variant":"normal", "weight":"normal", "family":"Arial" } } } ] } } ] } } ...

With the cloud based services it becomes difficult or impossible to pin down IPs, so adding the full range for each domain/sub-domain is probably the best option to ensure you have access to all the services. AWS might also even change the IP ranges according to this page: AWS IP Address Ranges - Amazon Web Services . But check with Esri and Amazon if you still have doubts about the security. ...
