Hi, I am using the Add Data widget in several apps. When adding a KML via the drop, it works in my workspace environment where I don't require a proxy to access the services. When the app is deployed to Test/Prod environments is uses the Esri resource-proxy to access the secured services, webmap, etc. I have rules in the proxy configured for
.
There browser error I get looks like this:
(index):1 Access to XMLHttpRequest at 'https://mydomain/portal/sharing/kml' from origin 'https://appdomain' has been blocked by CORS policy: The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.
AddFromFilePane.js?wab_dv=2.10:387 Unable to load KML
.
I've narrowed this down to the widget's use / lack of use of the proxy by disabling it temporarily (and ignoring layer load errors) and it does work when deployed to those web servers. What I don't get is that in both the working and problem environments, the requests look exactly the same in the network tab, so I'm not sure what is wrong. Any advice? Thanks!
