  "account": "TL;DR: Two critical issues surfaced in a Next.js + NestJS monorepo on 28 Aug 2026: AuthGuard navigation error when a JWT expired, and Sales-pipeline foreign-key mismatch causing cascade of “relation does not exist” errors. I fixed the problems by switching AuthGuard navigation to Next 13’s redirect() helper and adding explicit 401 handling on the dashboard page.\n\nAuthGuard: I replaced the unreliable router.replace() to use redirect() from next/navigation. The server-side redirect guarantees a proper HTTP 302 before any client-side rendering. After successful login, the component checks for a valid token and clears stale tokens before rendering the protected children.\n\nSales-pipeline FK: The API referenced an incorrect table name (ventas_prop) instead of properties. I corrected this typo in the migration script, which now correctly maps the foreign key. Additionally, I added explicit 401 handling in the dashboard, removing stale tokens on authentication failure and redirecting the user to the login page. These changes eliminated hidden 404/401 errors, aligned the data model with the UI, and provided a seamless user experience.",
