Invalid redirect_URI error Issue When making an OAuth 2.0 connection, getting an invalid redirect_url error for Copilot or any third-party integration. ReleaseAll releasesResolutionCopilot Studio is acting as a client requesting access to the ServiceNow instance, while ServiceNow functions as the authorization server. In Copilot or any third-party integration, the connection is configured using the Client ID and Client Secret defined in the OAuth registration(Application registery) on the ServiceNow side. When a request is made from Copilot to ServiceNow, ServiceNow validates the Client ID and Client Secret.Upon successful validation, ServiceNow attempts to redirect back with an authorization code to the Redirect URL specified in the OAuth registration. The issue arises because the Redirect URL configured in the Application Registry is incorrect. Please confirm the correct callback URL from the third-party vendor, as this must be registered in the Redirect URL field of the OAuth registration in the ServiceNow Application Registry. Note For testing purpose via Postman, Below is the callback URL which can also be used in the Redirect URL field for testing purposes (this is an open-source testing endpoint): https://oauth.pstmn.io/v1/browser-callback
