Laravel Errors
Laravel errors: 419 (CSRF token mismatch), QueryException, ModelNotFoundException, MassAssignmentException, ValidationException, InvalidArgumentException, MethodNotAllowedHttpException.
Laravel 419 = expired/invalid CSRF token (session timeout, mismatched cookie domain, stale form). QueryException wraps PDO errors. MassAssignmentException requires updating `$fillable` or `$guarded`. ValidationException returns JSON 422 in API contexts, redirects elsewhere. Queue jobs that fail get retried per `tries` config; check `failed_jobs` table.
