Expected: The deployment should complete successfully and go live, since the build itself finishes without errors. Current: The build compiles and generates all pages successfully, but the deployment fails immediately after with: Error: ENOENT: no such file or directory, lstat '/vercel/path0/.next/export-detail.json' This happens right after "Traced Next.js server files in: XXms" in the build logs.

Build logs excerpt: ✓ Compiled successfully ✓ Generating static pages (28/28) Traced Next.js server files in: 33.583ms Error: ENOENT: no such file or directory, lstat '/vercel/path0/.next/export-detail.json' What I've already tried (same error every time, no change in outcome):

• Removed vercel.json entirely (no crons config) — same error

• Tested with and without build cache — same error

• Changed Node.js version from 24.x to 22.x — same error

• Upgraded Next.js from 14.2.3 to 14.2.30 — same error

• Confirmed output: 'export' is NOT set in next.config.js

• Confirmed Framework Preset is explicitly set to "Next.js" (not "Other")

• Confirmed Build Command override is disabled (running default next build) next.config.js: /** @type {import('next').NextConfig} */ const nextConfig = {} module.exports = nextConfig

• Framework: Next.js (App Router only, no pages directory)

• Next.js version: 14.2.30 (also tested 14.2.3)

• Node.js version: tested on 22.x and 24.x

• Vercel CLI version (from logs): 54.19.0

• Plan: Hobby

• Deployment target: Production

• Build output includes both static (○) and dynamic (ƒ) routes, including multiple App Router route handlers under app/api/...
