How to store hashed passwords in firestore

so i want to save a user object in firestore, it's my first time working with firestore, so i use Bcrypt to encode the password than i save the object in firestore but it doesn't seem to be able to save it

This is my code

 * createUser
 * @param {string} email
 * @param {string} password
 * @param {string} name
 */
const createUser = async (email, password, name) => {
  const user = await getUser(email);
  if (user) throw new Error('User account already exists');

  bcrypt.genSalt(10, (salt) => {
    bcrypt.hash(password, salt, (hashedPassword) => {
      db.collection('users')
        .doc(email)
        .set({ hashedPassword, email, name });
    });
  });
};

and am getting this error

        throw new Error(validate_1.customObjectMessage(arg, value, path));
        ^

Error: Value for argument "data" is not a valid Firestore document. Input is not a plain JavaScript object (found in field "hashedPassword").

Most likely the hash is returns as a readable stream, in which case you can for example hex encode it with:

hashedPassword.toString("hex")
