[xdd825]

I try to run this command

yarn hardhat deploy --network rinkeby --tags main

and I got this error

NomicLabsHardhatPluginError: The constructor for contracts/DynamicSvgNft.sol:DynamicSvgNft has 3 parameters
but 0 arguments were provided instead.

my code below

this is my constructor in "DynamicSvgNft.sol" file

constructor(
        address priceFeedAddress,
        string memory lowSvg,
        string memory highSvg
    ) ERC721("Dynamic Nft Svg", "DNS") {
        s_tokenCounter = 0;
        i_lowImageURI = svgToImageURI(lowSvg);
        i_highImageURI = svgToImageURI(highSvg);
        i_priceFeed = AggregatorV3Interface(priceFeedAddress);
    }

this is my arguments and deploy script in "03-deploy-dynamic-svg-nft.js"

const args = [ethUsdPriceFeedAddress, lowSvg, highSvg]

const dynamicSvgNft = await deploy("DynamicSvgNft", {
        from: deployer,
        args: args,
        log: true,
        waitConfirmations: network.config.blockConfirmations || 1,
    })

[PatrickAlphaC]

Your ethUsdPriceFeedAddress, lowSvg, highSvg are likely all null right now. Can you do a console.log(lowSvg) and find out why they are null?

[xdd825]

Thanks for the reply Patrick, here is the lowSvg, highSVG, ethUsdPriceFeedAddress looks like

lowSvg

I clone and run the complete code on hardhat-nft-fcc it work fine. So I try copy the full RandomIpfsNft.sol and deploy-dynamic-svg-nft.js replace my code and it still show the errror. Maybe the problem is in other place ,but I still not figure out yet.

[PatrickAlphaC]

Where are your console.logs?

[adityabhattad2021]

Hey your error is in verify.js
in verify.js check if this is correct

 await run("verify:verify", {
            address: contractAddress,
            constructorArguments:args,
        })
