Common Errors
SvelteKitError3 reportsSvelteKitError often arises during `pnpm build` when `config.kit.prerender.handleHttpError` is set and a prerendered route encounters an unhandled HTTP error (like a 404). To fix this, either handle the error in your `handleHttpError` function, ensuring it returns a valid response, or remove `config.kit.prerender.handleHttpError` if you don't need custom error handling. Ensure all prerendered routes are accessible and return 200 OK responses during build.
UpdatedAtError1 reportThe "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.
