Fix UpdatedAtError

✅ Solution

The "UpdatedAtError" in SvelteKit with remote functions (like Supabase) usually indicates a mismatch or incorrect handling of `updated_at` (or similar) fields during data updates. Ensure your remote function and SvelteKit code consistently use the same data type and format for the `updated_at` field (often a timestamp string in ISO 8601 format), and correctly handle time zone differences between the server and client when updating or comparing these values. Also, verify that your database schema has `updated_at` configured to automatically update on changes.
