.connect() won't recognize signers from .getSigners()

[0xGenghisGoose]

I have been trying to resolve this for about 3 hours now and for the life of me I can't figure out why it's doing this. Just writing some simple tests for a simple prediction market dapp I put together today, and though I've followed the documentation on testing (with ethers + hardhat) and have written multiple tests in this format before, it doesn't seem to want to let me do it this time.

Relevant code from test:

const { expect } = require('chai');
const { ethers } = require('hardhat');

const BET = {
	MOON: 0,
	REKT: 1,
};

describe('PredictionMarket', () => {
	let addy1;
	let addy2;
	let addy3;

	it('Should allow a user to bet on either side & keep track', async () => {
		[addy1, addy2, addy3] = await ethers.getSigners();
		console.log(addy1);

		const oracleContract = await ethers.getContractFactory('Oracle');
		const oracle = await oracleContract.deploy();
		await oracle.deployed();
		console.log('Oracle address:', oracle.address);

		const predictionMarketContract = await ethers.getContractFactory(
			'PredictionMarket'
		);
		const predictionMarket = await predictionMarketContract.deploy(
			oracle.address
		);
		await predictionMarket.deployed();
		console.log('Prediction address:', predictionMarket.address);

		const firstBet = await predictionMarket.connect(addy1).makeBet(BET.MOON, {
			value: ethers.utils.parseEther('1'),
		});
		await firstBet.wait();

When I pass the SignerWithAddress (from getSigners) object to the connect function like above, I receive this error:

Error: invalid address or ENS name (argument="name", value="<SignerWithAddress my-address-here>", code=INVALID_ARGUMENT, version=contracts/5.5.0)

When I dot into the address (addy1.address) I receive this error:

Error: VoidSigner cannot sign transactions (operation="signTransaction", code=UNSUPPORTED_OPERATION, version=abstract-signer/5.5.0)

This is all just local, haven't tried to deploy on a testnet yet. Am I doing something blatantly wrong here that I've just been getting lucky with in the past? Can't seem to find anyone that has had similar issues either when looking around.

Appreciate any help at all here, this has been driving me crazy. Thank you!

It looks ok to me, just at a glance. What is the value of BET.MOON? Should it be an address? If so, is it? I’m not sure what the ABI looks like.

Thank you so much for the quick reply! BET.MOON is just a helper objest in my test file (mapped to 0 & 1) to stand for an enum choice in the smart contract (just moon or rekt; over/under); here's the helper:

const BET = {
	MOON: 0,
	REKT: 1,
};

Here's the function in my smart contract if that will help as well:

function makeBet(Bet _bet) external payable {
        require(poolClosed == false, "Bets for this pool are closed");
        bets[_bet] += msg.value;
        betsPerUser[msg.sender][_bet] += msg.value;
    }

I really do feel like it's all correct, I don't know why it's being fussy with me :/

Hey @0xGenghisGoose is the problem resolved for you? In case it's not, how are you running the tests? It's weird that VoidSigner is being pulled into, if you are using npx hardhat test, that should work.
