Description

Minimal sample with import:

import { CID } from 'multiformats';

async function main() {
    console.log(CID.parse('QmaozNR7DZHQK1ZcU9p7QdrshMvXqWK6gpu5rmrkPdT3L4'));
}
  
main().catch((error) => {
    console.error(error);
    process.exitCode = 1;
});

Getting:

Error: No "exports" main defined in /home/dag-json-demo/node_modules/multiformats/package.json
    at exportsNotFound (node:internal/modules/esm/resolve:304:10)

    at Object.<anonymous> (/home//dag-json-demo/scripts/demo/dag-json.ts:1:1) {
  code: 'ERR_PACKAGE_PATH_NOT_EXPORTED'
}

Expected behavior:
Import CID

Environment:

@ipld/dag-json v10.2.2,
node v20.12.2
npm 10.5.0
tsx v4.16.2

tsconfig.json

{
  "compilerOptions": {
    "target": "es2020",
    "module": "commonjs",
    "strict": true,
    "esModuleInterop": true,
    "resolveJsonModule": true,
    "outDir": "dist",
    "declaration": true,
    "typeRoots": ["./typechain-types", "./node_modules/@types"],
    "types": ["@nomiclabs/hardhat-ethers"]
  },
  "include": ["./scripts", "./test", "./typechain-types"],
  "files": ["./hardhat.config.ts"]
}

The same result with tsconfig.json

{
  "compilerOptions": {
    "target": "esnext",
    "module": "esnext",
    "strict": true,
    "outDir": "dist",
    "declaration": true,
    "typeRoots": ["./typechain-types", "./node_modules/@types"],
    "types": ["@nomiclabs/hardhat-ethers"]
  },
  "include": ["./scripts", "./test", "./typechain-types"],
  "files": ["./hardhat.config.ts"]
}

Research direction

Start with the import in scripts/demo/dag-json.ts and inspect multiformats/package.json, then reproduce the ERR_PACKAGE_PATH_NOT_EXPORTED error using Node 20, tsx, and the provided tsconfig.json variants. Done means the minimal sample can import CID and run without the reported package-resolution error.
