From bcf5c4c4aa167ac26940ca0555248ddb849530e8 Mon Sep 17 00:00:00 2001 From: Erik Johnston Date: Fri, 3 Jul 2026 15:15:42 +0000 Subject: [PATCH] Bind filter_id as an int in get_user_filter, matching the BIGINT column MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `get_user_filter` receives `filter_id` as `int | str` — from a sync request it arrives as a string — and bound it straight into the `user_filters.filter_id` BIGINT column. psycopg2 coerced the numeric string; the native Rust driver binds typed parameters and rejects it (error serializing parameter), 500ing filtered syncs. The function already validated it with `int(filter_id)`; use that value so an int is bound. psycopg2 and sqlite are unaffected.
