OAuth redirect issue - Known Error

OAuth redirect issue Description SSO, OAuth Redirect, Shows Error with code after Idle time instead of Refresh

When the Sk8s autocomplete service runs in Now Assist for Code and the user’s session expires, the periodic token‑refresh interval still attempts an OAuth flow. The fetch to /oauth_auth.do uses the expired session ID, causing the platform to store OAuth state and later replay it after the user logs back in. As a result, after login the browser is redirected through the OAuth chain to /api/sn_now_assist_code/code_assist_service_api/oauth_redirect, which returns raw XML instead of a normal page, leaving the user stranded.

Steps to Reproduce

1. Open a ServiceNow instance (Zurich) that has the Now Assist for Code scoped app installed and Sk8s autocomplete enabled 2. Open a script editor (e.g., a Business Rule or Script Include) — this initializes Sk8sAuthTokenService and starts the 4-minute refresh interval 3. Let the session expire without closing the tab (walk away, or manually expire the session server-side) 4. Do not refresh or navigate — leave the stale tab open 5. Wait for the next token refresh interval to fire (~4 minutes) — the old code calls oauth_auth.do with no active session, causing the platform to store the pending OAuth authorization state server-side 6. Log back in via a separate tab or by navigating to login.do

Workaround This issue has been fixed in Now assist for code v28.5.19, It is available from Zurich P8.
