Nothing in your deploy scripts jumps out as wrong to me. Upload the project repo; maybe I can help you track down the issue. |

@blaynejosh lets debug it together, try hardhat method const EthUsdAggregator = await deployments.get("MockV3Aggregator")
ethUsdPriceFeedAddress = EthUsdAggregator.address |

Okay here it is const { network, ethers } = require("hardhat")
const { developmentChains } = require("../helper-hardhat-config")
const { verify } = require("../utils/verify")
const fs = require("fs")
module.exports = async function ({ getNamedAccounts, deployments }) {
const { deploy, log } = deployments
const { deployer } = await getNamedAccounts()
const chainId = network.config.chainId
let ethUsdPriceFeedAddress
if (chainId == 31337) {
const EthUsdAggregator = await deployments.get("MockV3Aggregator")
// const EthUsdAggregator = await ethers.getContract("MockV3Aggregator")
ethUsdPriceFeedAddress = EthUsdAggregator.address
} else {
ethUsdPriceFeedAddress = networkConfig[chainId].ethUsdPricefeed
}
log("-------------------------------------------------------")
const daySvg = await fs.readFileSync("./images/dynamicSvgNft/daySVG.svg", { encoding: "utf8" })
const nightSvg = await fs.readFileSync("./images/dynamicSvgNft/nightSVG.svg", {
encoding: "utf8",
})
args = [ethUsdPriceFeedAddress, daySvg, nightSvg]
const dynamicSvgNft = await deploy("DynamicSvgNft", {
from: deployer,
log: true,
args: args,
waitConfirmations: network.config.blockConfirmations || 1,
})
if (!developmentChains.includes(network.name) && process.env.ETHERSCAN_API_KEY) {
log("Verifying...")
await verify(dynamicSvgNft.address, args)
}
}
module.exports.tags = ["all", "dynamicSvgNft", "main"] |

@blaynejosh megre the PR's from @abossofmyself After the commands that @abossofmyself recommends, you will run into an TransactionExecutionError: Transaction ran out of gas The out of gas error is caused by your daySVG and nightSVG; they are much too large to put on the blockchain without spending crazy amounts of gas. Use Patrick's happy.svg and frown.svg once you change out the svg you are using, you will get another error. To fix it, add a scripts folder to the project root and move 04-mint.js to the scripts folder |

@blaynejosh : Its correct, Your SVGs are huge! ^ Please use smaller size SVGs, Otherwise, It will gonna give you an error : Transaction ran out of gas! Merge the PRs and add smaller size SVGs in your project! And let me know, If the issue persists! |

@abossofmyself Thank you for your contributions on this repo and in discussions. As per a recent discussion with Patrick, We concluded that just making PRs to someone's code will not produce the optimal output and it is even worst in the long run for others. We have to guide them so they can solve their issues themselves and can learn from those mistakes and just making PRs will not help them at all. In the above issue, I could also make PR to his repo! Patrick messages;
So, I hope now we will follow this! @abossofmyself @krakxn Tag anyone else here whom you think should read this. |

@alymurtazamemon : That's nice! from now on, I will explain their problems in their discussions, So that other's can see the solutions of it as well, when they get into similar problems! and I totally understand Patrick's point on this: And he is absolutely correct! Explain their problem in their discussion, So they will at least try to fix that problem on their own and learn from it! |
