Description

Currently not directly consuming the mux library but via a nested dependency in my next app like so:

app -> dependency A -> dependency B -> @mux/mux-player-react

when trying to run next build, I get the following error:

Module not found: Default condition should be last one

https://nextjs.org/docs/messages/module-not-found

When I rearrange the exports from this:

  "exports": {
    ".": {
      "import": "./dist/index.mjs",
      "require": "./dist/index.cjs.js",
      "default": "./dist/index.cjs.js",
      "types@<4.3.5": "./dist/types-ts3.4/index.d.ts",
      "types": "./dist/types/index.d.ts"
    },
    "./lazy": {
      "import": "./dist/lazy.mjs",
      "default": "./dist/lazy.mjs",
      "types@<4.3.5": "./dist/types-ts3.4/lazy.d.ts",
      "types": "./dist/types/lazy.d.ts"
    },
    "./themes/*": {
      "import": "./dist/themes/*.mjs",
      "require": "./dist/themes/*.cjs.js",
      "default": "./dist/themes/*.cjs.js",
      "types@<4.3.5": "./dist/types-ts3.4/themes/*.d.ts",
      "types": "./dist/types/themes/*.d.ts"
    }
  },

to this:

  "exports": {
    ".": {
      "import": "./dist/index.mjs",
      "require": "./dist/index.cjs.js",
      "types@<4.3.5": "./dist/types-ts3.4/index.d.ts",
      "types": "./dist/types/index.d.ts",
      "default": "./dist/index.cjs.js"
    },
    "./lazy": {
      "import": "./dist/lazy.mjs",
      "types@<4.3.5": "./dist/types-ts3.4/lazy.d.ts",
      "types": "./dist/types/lazy.d.ts",
      "default": "./dist/lazy.mjs"
    },
    "./themes/*": {
      "import": "./dist/themes/*.mjs",
      "require": "./dist/themes/*.cjs.js",
      "types@<4.3.5": "./dist/types-ts3.4/themes/*.d.ts",
      "types": "./dist/types/themes/*.d.ts",
      "default": "./dist/themes/*.cjs.js"
    }
  },

the build is fixed.

Using node v18.14.2, next v14.2.18.

node docs seem to specify that default should always come last
Webpack docs also seem to infer that default should be the last condition but also to avoid it as it can be "handled differently between tooling"

Current Behavior

next build fails with Module not found: Default condition should be last one

Expected Behavior

next build should be successful
