I have a custom basemap gallery in ArcGIS Enterprise Portal.
I created basemap in JavaScript running on https://localhost:4200 ( local development server).
const basemap = new Basemap({
portalItem: {
id: "0560e29930dc4d5ebeb58c635c0909c9",
portal: {
url: "https://xxx.com/portal"
}
}
});
How to setup allowedorigins in Enterprise Portal?
Thanks.
