Question: What does Error 25004 mean during OAuth authentication?
This is a Nylas-specific error code and applies to all providers (Google, Microsoft, EWS, IMAP/iCloud) — it is not specific to any one provider.
Error 25004 (login_id_invalid) means the authentication session could not be found or has expired. The full error message is:
Login ID or request is invalid or has expiredHow authentication sessions work
When a user starts the Nylas hosted authentication flow, a login record is created and stored in a temporary cache with a time-to-live (TTL). This record tracks the authentication session as the user moves through the OAuth consent screen. Error 25004 means that by the time the authentication flow tried to retrieve this record, it was no longer available.
Common triggers:
Session Expiration: Taking too long (usually over 1 hour) to click "Allow" on the provider's consent screen.
Browser Refreshes: Manually refreshing the page during the redirect process, which can delete or lose the session ID.
Network Delays: Connectivity issues causing the authentication flow to timeout.
Duplicate Tabs: Starting the connection process in multiple tabs, which often invalidates earlier session attempts.
- Bookmarked URLs: Using saved authentication URLs from previous sessions
- Browser Cache/Cookies: Cached data interfering with session state
Malformed Links: Technical issues where the login ID is missing or not passed correctly in the URL.
User Resolution
Restart the Process: Begin the OAuth flow from the very beginning rather than refreshing or retrying the same session.
Avoid Refreshes: Wait for the authentication pages to load completely rather than manually refreshing the browser.
Act Promptly: Complete the login and consent steps without long delays to prevent the session from expiring.
Prevention: Avoid interrupting the process with browser navigation or multi-tabbing during the flow.
Check Service Status: If the issue affects multiple users, check the Nylas status page for ongoing service disruptions.
