Hello, I have an arcgis ArcGISDynamicMapServiceLayer with quite a big number of "layerDefinitions" applied with the "setLayerDefinitions" method.  The problem is that the GET export REST function of ArcGIS Server 10.4.1 (with webadaptor on IIS) does not work as the request is too big so a POST would be necessary. It is stated in the documentation that "If the layer definition expression is longer than approximately 2000 characters you will need to set up a proxy page.".  I configured the ESRI proxy GitHub project on my server and configured JS api (3.20) to always use the proxy: esriConfig.defaults.io.proxyUrl = "<url_to_proxy>" esriConfig.defaults.io.alwaysUseProxy = true; The problem is that requests are still sent as GET operation so it does not work as well. How am I supposed to tell JS API to POST for export map operation either directly to the REST api or to the proxy ? Thanks for your help, Nicolas ... View more

Hello, I just tested publishing vector tiles to AGOL and when testing it on various browsers I found out that my tiles were not displaying on an up to date Chrome for Android 55.0.2883.91. I thought at the beginning that it could come from my package so I switched to a very basic map with js api 4.2 using ESRI Vector tiles: map = new Map({ basemap: 'streets-navigation-vector' }); It turns out that they do not display as well. The debugger is full of the following warnings: "Data type is uint however extension OES_Element_index_unit is not supported therefore this draw call cannot be made." The browser is up to date and for example Mapbox vector tiles display properly either v8 or v9: var map = new mapboxgl.Map({ container: 'map', style: 'mapbox://styles/mapbox/streets-v8' }); So finally, I decided to switch to 4.1 ESRI JS API and it worked ! ESRI vector tiles displayed properly. Problem is that my vector tiles are not projected in WGS84 Web Mercator (auxiliary sphere) and it seems that it was not supported at 4.1. Hopefully it will be fixed in 4.3. This brings me to a second point : is it planned in ESRI JS API to detect if client support vector tiles ? Thanks, Nicolas ... View more

Hello, I think it would be good to add support for tileServers for basemap defined in AGOL or more generally in the webappconfig json.  As it seems that it cannot be done on the server side contrary to what ESRI REST API documentation state: Define tile servers of tiled map services  ArcGIS Server REST API  So far it can only be used with defining an ArcGISTiledMapServiceLayer : ArcGISTiledMapServiceLayer | API Reference | ArcGIS API for JavaScript 3.19  So it cannot be easily integrated in the WebAppBuilder.
