現象

npx hardhat run scripts/deploy.js --network sepolia

で下記エラーが発生

TypeError: no matching function (argument="key", value="deployed", code=INVALID_ARGUMENT, version=6.6.0)

  argument: 'key',
  value: 'deployed'
}

deploy.jsの、await transactions.deployed(); でエラーが出ているとのこと

解決策

下記の方法でうまくいきました。

deploy.js（旧ver）
// import { ethers } from "hardhat";
const ethers = require("hardhat").ethers;

const deploy = async () => {
	const Transactions = await ethers.getContractFactory("Transactions");
	const transactions = await Transactions.deploy();
	await transactions.deployed();

	console.log("Transaction deployed to:", transactions.address);
}

const runDeploy = async () => {
	try {
		await deploy();
		process.exit(0);
	} catch (err) {
		console.log(err);
		process.exit(1);
	}
}

runDeploy();

↓↓↓↓

deploy.js（2023/06/22現在）
const {ethers} = require("hardhat");

const deploy = async () => {
	const transactions = await ethers.deployContract("Transactions");
	await transactions.waitForDeployment();
	console.log("成功！ Transaction deployed to:", transactions.target);
}

const runDeploy = async () => {
	try {
		await deploy();
		process.exit(0);
	} catch (err) {
		console.log(err);
		process.exit(1);
	}
}

runDeploy();

原因

どこかのタイミングで、書き方が変わったようですね

旧
	const Transactions = await ethers.getContractFactory("Transactions");
	const transactions = await Transactions.deploy();
	await transactions.deployed();
新
	const transactions = await ethers.deployContract("Transactions");
	await transactions.waitForDeployment();

新しい記法の方が圧倒的にシンプルで良いですね。
