From 650763bdc8e47b00e097a4f129bfb7421f6d2b94 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Dean=20Qui=C3=B1anola?= Date: Wed, 25 Mar 2026 13:02:13 -0700 Subject: [PATCH 1/6] fix(runtime): handle input=None in generic handler gracefully `job.get("input", {})` returns None when input is explicitly null, causing AttributeError on the subsequent `.get()` call. Use `or {}` to coalesce both missing and null input to empty dict.
