The Contracts were deployed successfully. But for minting the NFTs, first I'm getting error with ethers.getContract is not a function so I add yarn add --dev hardhat @nomiclabs/hardhat-ethers@npm:hardhat-deploy-ethers ethers@^0.3.0-beta.13 and now I'm getting this.

The mint file:

const { ethers, network } = require("hardhat")

const PRICE = ethers.utils.parseEther("0.1")

async function mintAndList() {
    const nftMarketplace = await ethers.getContract("NFTMarketplace")
    const randomNumber = Math.floor(Math.random() * 2)
    let basicNft = await ethers.getContract("BasicNFT")
    
    console.log("Minting NFT...")
    const mintTx = await basicNft.mintNft()
    const mintTxReceipt = await mintTx.wait(1)
    const tokenId = mintTxReceipt.event[0].args.tokenId
    console.log("Approving NFT...")
    const approvalTx = await basicNft.approve(nftMarketplace.address, tokenId)
    await approvalTx.wait(1)
    console.log("Listing NFT...")
    const tx = await nftMarketplace.listItem(basicNft.address, tokenId, PRICE)
    await tx.wait(1)
    console.log("NFT Listed!")
}

mintAndList()
    .then(() => process.exit(0))
    .catch((error) => {
        console.error(error)
        process.exit(1)
    })

Please help me 🙏

try install new version of ethers with yarn add --dev ethers@5.7.2 and then run your code
