# Error: The operation was aborted. (Edge Runtime) / fetch failed: aborted

- **ID:** `nextjs/edge-runtime-fetch-aborted`
- **Domain:** nextjs
- **Category:** runtime_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

A fetch request in the Edge Runtime (middleware or edge function) exceeded the 30-second timeout or was aborted due to a resource limit, causing the request to be terminated prematurely.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| Next.js 14.0.0 | active | — | — |
| Next.js 14.1.0 | active | — | — |
| Next.js 14.2.0 | active | — | — |
| Vercel Edge Runtime 2024 | active | — | — |

## Workarounds

1. **Move the fetch logic to a Server Component or API route that runs on Node.js, which has no 30-second timeout limit. Example: create an API route at app/api/proxy/route.ts that performs the fetch and call it from the edge middleware.** (85% success)

2. **Optimize the fetch target to respond faster (e.g., add caching headers, reduce payload size, or use a CDN). Also ensure the fetch uses a reasonable timeout like { signal: AbortSignal.timeout(25000) } to fail gracefully before the hard limit.** (75% success)

## Dead Ends

- **** — The Edge Runtime has a hard 30-second timeout per request that cannot be overridden by client-side timeout options; the platform enforces this limit. (90% fail)
- **** — XMLHttpRequest is not available in the Edge Runtime; only fetch and a subset of Web APIs are supported. (100% fail)
- **** — The underlying timeout or resource limit will still apply on each retry, and infinite retries can exhaust memory or cause cascading failures. (70% fail)
