Hono.js Vercel runtime have problems with bcrypt.js and bcrypt

Question

Normally we can't use bcrypt in edge functions. So when using bcrypt.js

    const salt = bcrypt.genSaltSync(10);
    const hash = bcrypt.hashSync(password, salt);

This produces an error

    TypeError: import_bcryptjs.default.genSalt is not a function]

This error throws for everything (hash, hashsync, gensalt, gensaltsync)

I expected this to work normally but as I mentioned above it throws an error

    TypeError: import_bcryptjs.default.genSalt is not a function]

I have installed

    bun i @types/bcryptjs

and

    bun i bcryptjs

so I don't know what's the problem and it's not a typo error.

So Then I tried @fntools/password a npm package which works well. @fntools/password npm package

well then is there something I'm missing in bcrypt.js? my tsconfig.js -->

{
  "compilerOptions": {
    "target": "ESNext",
    "module": "ESNext",
    "moduleResolution": "node",
    "esModuleInterop": true,
    "skipLibCheck": true,
    "strict": true,
  },
}

my vercel.json -->

{
  "rewrites": [
    {
      "source": "/api/(.*)",
      "destination": "/api"
    }
  ]
}

working code -->

import PasswordHasher from "@fntools/password";
const encrypt = new PasswordHasher(10);

export const HashPass = (password: string) => {
    const hashedPassword = encrypt.hash(password);
    console.log(hashedPassword);
    return hashedPassword;
};
