From 346245d86002605fb942a20b50f1474c859f9421 Mon Sep 17 00:00:00 2001 From: "Molecule AI Dev Engineer A (Kimi)" Date: Sun, 7 Jun 2026 21:52:21 +0000 Subject: [PATCH 1/4] fix(channels): remove duplicate EncryptSensitiveFields + add rows.Err test (#1221) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit **CWE-312 fix:** ChannelHandler.Create() had two consecutive EncryptSensitiveFields calls (lines 159-172). The second was a pure no-op that wasted CPU and confused readers. Removed the duplicate. **Test:** Add TestChannelHandler_List_RowsErr_LogsError to verify that a mid-stream rows.Err() after the Next() loop is logged but non-fatal — the handler still returns the successfully-scanned row(s) with HTTP 200. The rows.Err() checks in List() and Webhook() were already present from PR #1900; this commit completes the issue by removing the duplicate encryption and adding the missing regression test.

Add TestChannelHandler_Create_EncryptsSensitiveFields with sqlmock custom matcher that verifies the INSERT configJSON carries bot_token prefixed with ciphertextPrefix (ec1:). Sets SECRETS_ENCRYPTION_KEY + resets crypto state so the test exercises real encryption rather than the dev plaintext fallback.
