User.comparePassword is not a function, what should I do?

Question

MongoDB

Displays

{
    "message": "User.comparePassword is not a function"
}

Here is the part of the code with comparePassword:

UserSchema.methods.comparePasswords = async function (password) {
  return await bcrypt.compare(password, this.password);
}

Answer 1

"User.comparePassword is not a function"

Since the method should actually be called, what number should the passwords be in singular or plural? You already decide. Or do you not see the difference between comparePassword and comparePasswords?
