I’m a newcomer in NWC and Azure. Recently I found an example in Nintex Xtension gallery: https://gallery.nintex.com/t/sharepoint-online-additional-web-actions
I followed the steps in article to create this Xtension and asked my Azure admin to grant permission of SharePoint Online API Permission in Azure. However, the error said when I clicked add a connection in NWC that “The authorization server encountered an unexpected condition that prevented it from fulfilling the request.”
I’ve managed to change my security objects or even the authentication of redirect URI. In Configure platforms if I chose from Web to SPA(single-page application), the error said “the Proof Key for Code Exchange is required for cross-origin authorization code redemption.”
Did anyone have any idea? Thank you!
