Hey guys, I am trying to deploy an upgradable contract via hardhat and I am getting errors like
Artifact for contract "@openzeppelin/contracts/token/ERC20/ERC20.sol:ERC20" not found.

I used the hardhat flatten keyword to get the code flattened as I was using open zeppelin contracts, can anyone help me with this?

Well you need the ERC20Upgradable if you want the contract to be upgradable

Yes I have added that, everything is upgradable, still it is giving me this error

How does you deploy script look like

Via deployproxy

Share that deploy.ts (use pastebin or such)

Its gotta be using the wrong artifact

Yes on it, that ms grim

async function main() {
// Hardhat always runs the compile task when running scripts with its command
// line interface.
//
// If this script is run directly using node you may want to call compile
// manually to make sure everything is compiled
// await hre.run('compile');
// We get the contract to deploy
const GamiTestToken = await ethers.getContractFactory("GamiTestToken");
const GamiTestTokenProxy = await upgrades.deployProxy(GamiTestToken, { kind: 'uups', initializer: 'initialize' });
console.log("Gami Token deployed to:", GamiTestTokenProxy.address);
}
