From 147876f3389ae757e14297c48ad17edc2fe0e621 Mon Sep 17 00:00:00 2001 From: Molecule AI Fullstack Engineer Date: Fri, 15 May 2026 00:17:04 +0000 Subject: [PATCH 1/2] fix/approvals: log and guard json.Marshal error before DB insert Bug: json.Marshal returns []byte{} (empty slice, NOT nil) on error, so the old `if ctxJSON == nil` guard never fired. The error was silently ignored and an empty/zero byte slice was passed to the DB. Fix: check `err != nil` explicitly, log it, and fall back to "{}". Also add a defensive `len(ctxJSON) == 0` guard as in-depth defense. Add TestApprovals_Create_NilContextFallsBackToEmptyJSON to cover the nil-context path (was entirely untested) and document the expected SQL binding behavior.
