Summary

vinext build + vinext start crashes at startup when the app uses ImageResponse from next/og.

Error

Error [ERR_MODULE_NOT_FOUND]: Cannot find package 'a' imported from
  /path/to/dist/server/assets/yoga-sbSbVeWy.wasm

Context

The Yoga WASM file (used by Satori for OG image generation) is emitted into dist/server/assets/ during build, but contains a minified import reference ('a') that wasn't resolved during bundling. Node can't resolve it at runtime.

The app imports ImageResponse from next/og in several opengraph-image.tsx files.

Steps

Add an opengraph-image.tsx that uses ImageResponse from next/og
vinext build
vinext start
Crashes immediately with the above error
