Lesson 15 - Test issue (Assertion Error)

[DaurenNox]

Hey guys, having an issue with assert(listing.seller.toString() == deployer.address)

Here is the error: AssertionError: Unspecified AssertionError

I have checked the repo and Patrick has it the same.

Here is the code:

const {assert, expect, util} =require("chai")
const {network,deployments, ethers,getNamedAccounts } = require("hardhat")
const {developmentChains} = require("../../helper-hardhat-config")

!developmentChains.includes(network.name) 
? descibe.skip

    beforeEach(async function () {
        deployer = (await getNamedAccounts()).deployer
