Uncaught (in promise) TypeError: Cannot read properties of undefined (reading \'super\') Vuelidate

Question

第一次使用vuelidate，所以我不知道我可能做错了什么，我一直收到错误，我不确定它是否与语法或什么有关

import { useVuelidate } from "@vuelidate/core";
import { required, email } from "vuelidate/lib/validators";

export default {
  setup() {
    return { v$: useVuelidate() };
  },

  data: () => ({
    userData: {
      firstName: "",
      lastName: "",
      phone: "",
      email: "",
      password: "",
      confirmPassword: "",
    },
    submitted: false,
  }),
  validations() {
    return {
      firstName: { required }, 
      lastName: { required },
      contact: {
        email: { required, email }, 
      },
    };
  },
};
