Here's what I'm using: JSAPI v3.20 ArcGIS Server 10.3 ASP.NET Proxy 1.1.0 ASP.NET 4.0 I am having an issue when printing a map using Print (Print | API Reference | ArcGIS API for JavaScript 3.20 ). This occurs only after entering an address into the Search widget, and then plotting the result - the request is blocked during any export attempt after this action. The issue "Unexpected token <" results from the API expecting a JSON response, but getting an HTML page... the page in question is a custom error page capturing a Microsoft validation issue with "potentially dangerous content". Here's the request going through Fiddler: { "mapOptions": { "showAttribution": false, "extent": { "xmin": -9758929.205244847, "ymin": 5153837.351343746, "xmax": -9757291.78077969, "ymax": 5155062.73245334, "spatialReference": { "wkid": 102100, "latestWkid": 3857 } }, "spatialReference": { "wkid": 102100, "latestWkid": 3857 }, "scale": 4513.98870499674 }, "operationalLayers": [{ "id": "layer0", "title": "layer0", "opacity": 1, "minScale": 591657527.591555, "maxScale": 70.5310735, "url": "https://services.arcgisonline.com/ArcGIS/rest/services/Canvas/World_Light_Gray_Base/MapServer" }, { "id": "map_graphics", "opacity": 1, "minScale": 0, "maxScale": 0, "featureCollection": { "layers": [{ "layerDefinition": { "name": "pointLayer", "geometryType": "esriGeometryPoint" }, "featureSet": { "geometryType": "esriGeometryPoint", "features": [{ "geometry": { "x": -9758110.34234326, "y": 5154449.96419052, "spatialReference": { "wkid": 102100, "latestWkid": 3857 } }, "attributes": { "Addr_type": "StreetName", "Match_addr": "Main Ave, Chicago, Illinois, 60613", "StAddr": "Main Ave", "City": "Chicago", "score": 100, "searchTheme": "arcgisSearch", "searchResult": "Main Ave, Chicago, Illinois, 60613", "searchMoreResults": "moreResults", "searchMoreResultsItem": "moreItem", "searchMoreResultsId": "search_more_results", "searchMoreResultsHtml": "" }, "symbol": { "angle": 0, "xoffset": 6.75, "yoffset": 13.5, "type": "esriPMS", "url": "https://js.arcgis.com/3.20/esri/dijit/Search/images/search-pointer.png", "width": 27, "height": 27 }, "infoTemplate": { "title": "Search result", "content": "<div class=\"${searchTheme}\"><div id=\"${searchMoreResultsId}\" class=\"${searchMoreResults}\"><div class=\"${searchMoreResultsItem}\">${searchResult}</div><div>${searchMoreResultsHtml}</div></div></div>" } }] } }] } }, { "id": "layer1", "title": "layer1", "opacity": 1, "minScale": 591657527.591555, "maxScale": 70.5310735, "url": "https://services.arcgisonline.com/ArcGIS/rest/services/Canvas/World_Light_Gray_Reference/MapServer" }], "exportOptions": { "outputSize": [800, 1100], "dpi": 96 }, "layoutOptions": { "titleText": "My map title", "copyrightText": "My map copyright text", "scaleBarOptions": { "metricUnit": "esriKilometers", "metricLabel": "km", "nonMetricUnit": "esriMiles", "nonMetricLabel": "mi" }, "legendOptions": { "operationalLayers": [] } } }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...it appears the info window content HTML is the culprit. In my proxy web.config, if I revert validation to 2.0: <httpRuntime requestValidationMode="2.0" />‍‍ ...the request works. This is because .NET 2.0 only validates page requests, whereas 4.0 validates ALL HTTP requests. I'd like to call it a day and just implement the web.config change, but I'm wary about making such a modification due to XSS/security concerns. I thought about maybe encoding/decoding, but there doesn't seem to be a way to do this without modifying the JSAPI directly. Anyone have any ideas? Geonet is pretty quiet about this issue... Is it a bug? Print works fine otherwise! Thank you! ... View more
