project:/contracts/UniswapV2Library.sol:5:1: ParserError: Source "@openzeppelin/contracts/math/SafeMath.sol" not found import "@openzeppelin/contracts/math/SafeMath.sol"; ^-------------------------------------------------^

nothing in the package.json for openzeppelin

I successfully run this code in remix and I was confused about what type of value I can pass here to get the flash loan. I need an explanation about this contract.

Hey, I'm pretty new to the smart contract world - a lot of take in for sure. I've deployed your contract to mainnet and I'm trying to execute it but receiving a "execution reverted: Unauthorized" error. It looks like it might be from this line:

  require(msg.sender == UniswapV2Library.pairFor(factory, token0, token1), "Unauthorized"); 

Any ideas what I could be missing? My wallet private key is correct and matches the account that deployed the flash contract.

provider.on('block', async (blockNumber) => {
try {
console.log(blockNumber);
const sushiReserves = await sushiEthDai.getReserves();
const uniswapReserves = await uniswapEthDai.getReserves();
[...]
}
}
