Can't deploy FundMe, invalid bytecode

[Sanchez7599]

This is my deploy script:

const { networkConfig, developmentChains } = require("../helper-hardhat-config")
const { network } = require("hardhat")

module.exports = async ({ getNamedAccounts, deployments }) => {
    const { deploy, log } = deployments
    const { deployer } = await getNamedAccounts()
    const chainId = network.config.chainId

    let ethUsdPriceFeedAddress
    if (developmentChains.includes(network.name)) {
        const ethUsdAggregator = await deployments.get("MockV3Aggregator")
        ethUsdPriceFeedAddress = ethUsdAggregator.address
    } else {
        ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"]
    }

    const fundMe = await deploy("FundMe", {
        from: deployer,
        args: [ethUsdPriceFeedAddress],
        log: true,
    })
    log("_____________________________________________________________")
}

module.exports.tags = ["all", "fundme"]

After typing yarn hardhat deploy Mocks are being deployed and then I get this error:

Nothing to compile

Does anyone have the same issue?

[Sanchez7599]

I just realized that this issue was already loged and solved.

[RyanPaulGannon]

Yo, how did you fix this? I've looked through the issues and can't find anything? Getting the same error, using TypeScript.

[RyanPaulGannon]

All sorted, my PriceConverter.sol had functions set to public rather than internal!
