File won't get deployed? (HardhatError: HH700: Artifact not found.) - solidity

Question

I'm following this tutorial here: https://ethereum.org/en/developers/tutorials/hello-world-smart-contract-fullstack/ and I'm stuck with this error message:
HardhatError: HH700: Artifact for contract "HelloWorld" not found.
From what I found on the forums it seems to be a naming problem but the name for the contract & what is being deployed is the same:
pragma solidity >=0.7.3;
contract HelloWorld {
event UpdatedMessages(string oldStr, string newStr);
string public message;
constructor(string memory initMessage) {
message = initMessage;
}
function update(string memory newMessage) public {
string memory oldMsg = message;
message = newMessage;
emit UpdatedMessages(oldMsg, newMessage);
}
}
and this is the deploy.js file:
async function main() {
const HelloWorld = await ethers.getContractFactory("HelloWorld")
// Start deployment, returning a promise that resolves to a contract object
const hello_world = await HelloWorld.deploy("Hello World!")
console.log("Contract deployed to address:", hello_world.address)
}
main()
.then(() => process.exit(0))
.catch((error) => {
console.error(error)
process.exit(1)
})
When I compile it just says "Nothing to compile" and running this command: npx hardhat run scripts/deploy.js --network ropsten given mentioned HH700 error.
Can anyone please help?

Answer 1

const hello_world = await HelloWorld.deploy("Hello World!")
should be
const hello_world = await deploy("HelloWorld!")

Answer 2

Could be that you are missing the “npx hardhat compile” before the test. The artifacts are created when you compile.
