Root Cause

In the Edge Runtime (e.g., middleware, edge API routes), fetch requests have a default timeout of 30 seconds and can be aborted by the runtime if the response is too slow or if the client disconnects.

中文

在边缘运行时（例如中间件、边缘 API 路由）中，fetch 请求默认超时为 30 秒，如果响应太慢或客户端断开连接，运行时可能会中止请求。

Workarounds

  1. 80% success Optimize the external API response time (e.g., use caching, reduce payload size) to ensure it completes within 30 seconds. Alternatively, use a server-side data fetching pattern with incremental static regeneration (ISR) to avoid real-time fetch.

Dead Ends

Common approaches that don't work:

  1. 80% fail

    The Edge Runtime has a hard limit of 30 seconds for fetch; this cannot be overridden. The config option may not exist or be ignored in edge.

  2. 70% fail

    The runtime will still abort at 30 seconds even if the AbortController signal is set to a longer timeout.

  3. 50% fail

    If the route is already on edge, the runtime is fixed; moving to Node.js may require other changes (e.g., removing edge-specific APIs).
