// Regression guard for #5991 — clicking "Update now" showed an "Internal Server
// Error" screen (Minified React error #31). The handler POSTs /api/system/version
// (a loopback-only auto-update endpoint) and, on a non-OK JSON response, did:
//     notify.error(data.error || "Failed to start update.");
// OmniRoute's error envelope is `{ error: { code, message, correlation_id } }`, so
// `data.error` is an OBJECT. notify.error rendered that object as a React child →
// React #31 crash. The fix funnels the body through extractApiErrorMessage() (the
// same helper introduced in #5340) so a string always reaches the toast.
