SSIA :)
I have a site with 2 very similar XML libraries, one of which has at least 1 Query data connection; the other library is the one used for the SharePoint Library Submit DC, but when I try to create a Query DC for it, it cannot get its list of columns ("Encountered an error when retrieving columns: Failed to fetch"). It seems be running afoul of CORS:
Access to fetch at 'https://login.microsoftonline.com/3456fe92-cbd1-406d-b5a3-5364bec0a833/oauth2/v2.0/authorize?...' (redirected from 'https://formsv.nycourts.gov/WebProxy/GetColumnsByListId?...')
from origin 'https://formsv.nycourts.gov' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

What can I do to query this library?
