[umairahmed88]

i tried to solve this but unable to find bugs please help me

i got this error

TypeError: basicNft.mintNft is not a function
at Object.module.exports [as func] (hardHat/hardhat-nft/deploy/04.mint.js:8:37)

this is my code

const { ethers, network } = require("hardhat");
const { developmentChains } = require("../helper-hardhat-config");

module.exports = async function ({ getNamedAccounts }) {
const { deployer } = await getNamedAccounts();

const basicNft = await ethers.getContract("BasicNft", deployer);
const basicMintTx = await basicNft.mintNft();
await basicMintTx.wait(1);

console.log(`Basic NFT index 0 has tokenURI: ${await basicNft.tokenURI(0)}`);

const randomIpfsNft = await ethers.getContract("RandomIpfsNft", deployer);
const mintFee = await randomIpfsNft.getMintFee();

await new Promise(async (resolve, reject) => {
	setTimeout(resolve, 300000);
	randomIpfsNft.once("NftMinted", async function () {
		resolve();
	});

	const randomIpfsNftMintTx = await randomIpfsNft.requestNft({
		value: mintFee.toString(),
	});

	const randomIpfsNftMintTxReceipt = await randomIpfsNftMintTx.wait(1);

	if (developmentChains.includes(network.name)) {
		const requestId =
			randomIpfsNftMintTxReceipt.events[1].args.requestId.toString();
		const vrfCoordinatorV2Mock = await ethers.getContract(
			"VRFCoordinatorV2Mock",
			deployer
		);
		await vrfCoordinatorV2Mock.fulfillRandomWords(
			requestId,
			randomIpfsNft.address
		);
	}
});
console.log(
	`Random IPFS NFT index 0 tokenURI: ${await randomIpfsNft.tokenURI(0)}`
);

const highValue = ethers.utils.parseEther("4000");
const dynamicSvgNft = await ethers.getContract("DynamicSvgNft", deployer);
const dynamicSvgNftMintTx = await dynamicSvgNft.mintNft(highValue.toString());
await dynamicSvgNftMintTx.wait(1);
console.log(
	`Dynamic SVG NFT index of tokenURI: ${await dynamicSvgNft.tokenURI(0)}`
);

};

That's mintNFT not mintNft...

See:

    function mintNFT() public returns (uint256) { 
         _safeMint(msg.sender, s_tokenCounter); 
         s_tokenCounter = s_tokenCounter + 1; 
         return s_tokenCounter; 
     }

Answer:

const basicMintTx = await basicNft.mintNft(); // ❌
const basicMintTx = await basicNft.mintNFT(); // ✅
