v0.13.0 breaks existing NextJS build due to main vs. module change:

[CinchBlue]

🐛 Bug description

When building using v0.13.0 vs. v0.12.1, our existing NextJS/wasm-pack build process will break within CI with an opaque error message.

Run npm run build

> [email protected] build
> next build

  ▲ Next.js 14.2.4

   Linting and checking validity of types ...
   Creating an optimized production build ...
created symlink /runner/_work/app/app/.next/server/static -> /runner/_work/app/app/.next/server/chunks/static
created symlink /runner/_work/app/app/.next/static -> /runner/_work/app/app/.next/server/static
Failed to compile.

Error: ENOENT: no such file or directory, mkdir '/runner/_work/app/app/.next/static/media'

🤔 Expected Behavior

It should continue to work?

👟 Steps to reproduce

Use a package.json that looks like this, then try to use an NPM package build with wasm-pack 0.13.0 with this:

This seems related to this change in v0.13.0:

• Declare ES module in package.json - gthb, Add type = "module" in package.json to support nodejs in bundler mode #1039, fix: declare ES module in package.json #1061

[IceTDrinker]

can confirm this change is causing some issues on our end (the change of declared module type), is there a way to select the type of the output package ?
