I have a web app that contains two lines to add a cors enabled servers via the corsEnabledServers.push(<mydatasource page url here>); command . This works fine in Chrome and Firefox but Edge throws the following errors:
esri.config.defaults.io.proxyUrl is not set.
I am not sure how to proceed from here. The page I am trying to add is running IIS and has the proper web.config file. Any pointers would be appreciated.
