Next.js issue building for production because of ort-wasm-simd-threaded.mjs

Hi, I maintain a library that depends on onnxruntime-web that people frequently use with nextjs. I maintain a nextjs example here. However, I am struggling to package it properly. Right now, I copy all the necessary wasm files to the public directory using a webpack plugin. It does run properly using next's "dev" script, but when I try to create a production build using the build script, I get the error shown below. Is there an official nextjs example? Do you have any tips for packaging onnxruntime-web within nextjs apps?

> Build failed because of webpack errors

Start with examples/nextjs/next.config.js and the webpack plugin that copies files into public, then reproduce the failure with the example's next build script. Compare the handling of public/ort-wasm-simd-threaded.mjs during development and production builds; done means the Next.js production build completes without the reported Terser parse error.
