Missing redirect URL in application registration.” during OAuth 2.0 authorization.

[ZhenYangH]

Hello,

We are testing a scenario where an external application (Microsoft 365 side, Microsoft Search connector/Copilot) connects to ServiceNow Knowledge via OAuth 2.0. Reference:
https://learn.microsoft.com/ja-jp/microsoftsearch/servicenow-knowledge-connector

Following the video, at 1:07 when clicking “Authorize,” a popup shows:
Error message:
Missing redirect URL in application registration.
and we cannot proceed.

From the perspective of an external app connecting to ServiceNow, we suspect:

OAuth 2.0 misconfiguration on the external app or ServiceNow side (missing/mismatched redirect URI, platform type, ID/access token settings, tenant configuration, etc.)
Insufficient ServiceNow roles/permissions (roles required for Knowledge access and API authorization)

Any guidance or documentation from the standpoint of connecting an external app to ServiceNow would be greatly appreciated.
Thank you.

You may need the Redirect URL
https://gcs.office.com/v1.0/admin/oauth/callback

looks the same for Japan, too
