Organization invitation fails: expired invites, wrong org, JIT membership

TL;DR: Symptom: invite link errors or the user lands outside the org. Cause: expired invitation, email mismatch, or the login skipped the organization context. Verify New invite to a test email, accept in incognito, confirm membership in the dashboard and the organization claim in the token.

The error

invitation not found/expired

The fix

1. Expired: invitations expire after 7 days. Old links die.
2. Email mismatch: the invite is bound to an email; logging in with a different email (or a social account with a different email) fails acceptance.
3. Already accepted or already a member: re-invites error.
4. The accept login did not carry the organization context (invitation + organization params both required on the authorize call).
5. Connection mismatch: invite specifies a connection; user authenticated via another.
6. Organizations > your org > Members > Pending invitations: status and expiry.
7. Tenant logs: the failed acceptance event names the reason (expired, email mismatch).
8. The login event: does it carry the organization id? If not, the app dropped the context.
9. Resend the invitation for expired ones; confirm the email matches the user's login identity first.
10. Have the app pass both invitation and organization on the authorize call.
11. For high-volume onboarding, switch to just-in-time membership on the org's connections and skip invites entirely.
