From 38f6eab9d26f2d50d85287fe584f41ed7c81b0d4 Mon Sep 17 00:00:00 2001
From: Jeffrey Sica <me@jeefy.dev>
Date: Wed, 7 Oct 2026 19:54:38 -0500
Subject: [PATCH] fix: print the payload, not [object Object], when a command
 has no issue or pull number

18 handlers interpolated `${context.payload}` into their "github context
payload missing issue/pull/pr number" error, which renders as
`[object Object]`. They now use `JSON.stringify(context.payload)`, the
convention the other 9 "missing ..." errors already follow. The message
prefix and the thrown error types are unchanged.

A parametrized test drives each of the 18 sites with a payload lacking the
number and asserts the exact message and the absence of `[object Object]`.
