TypeError: Cannot read properties of undefined (reading 'equal') and also in truffle console when i try to see the number of candidates it is also undefined. is there any problme with the command (.candidatesCount().toNumber)?

const { assert } = require("assert");


var Election = artifacts.require("./Election.sol");

contract("Election", function (acc) {
  it("initializes with two candidates", function () {
    return Election.deployed()
      .then(function (ins) {
        return ins.candidatesCount();
      })
      .then(function (count) {
        assert.equal(count, 2);
      });
  });
});
