# Log: Clarified Network Fetch Errors During Compilation

**Trigger**: User reported TypeError: Failed to fetch during dev server hot-reload
**Date**: 2026-07-23 09:10 WIB

## Analysis

The client-side TypeError: Failed to fetch errors happen because Next.js compilation momentarily blocks or restarts the local API routing listener on port 3000 when file changes are saved. The browser's automatic polling/auto-refresh timers triggered exactly during this transition window, resulting in failed fetch requests.

## Status

Once the compilation completes successfully (Compiled in 162ms), the server routes are fully active. Refreshing the browser resolves the fetch errors instantly.
