Subject: newbie on EDS, form shows empty select list
Greetings, I set up a page in my app to use Embedded Discovery Service, with guidance from https://shibboleth.atlassian.net/wiki/spaces/EDS10/overview?homepageId=2383446015

My page happily displays the boilerplate red-bordered form for selecting an organization.

But the dropdown is empty. For detail, below is the modified idpselect_config.js that I am using. I’ve been trying minor variations of the values I specified, so far to no avail. (For (more) sanity, I defined my ‘magic strings’ in this file only once.) Any clues why my dropdown is empty?

Thanks, - Carl
