Lesson 5 -> Error: cannot estimate gas; transaction may fail or may require manual gas limit when deployed to Goerli Testnet

[zubeirarhesta]

I'm sorry for may bad english,
I've searched on google and read github discussions related to this matter, but didn't find any solution yet, except in #3308
but mine is when I tried to deploy to Goerli tesnet with my metamask account, not to Ganache like in #3308

Here is my deploy.js:

const ethers = require("ethers")
const fs = require("fs-extra")
require("dotenv").config()

async function main() {
    console.log("hi")
    const provider = new ethers.providers.JsonRpcProvider(process.env.RPC_URL)
    const encryptedJson = fs.readFileSync("./.encryptedKey.json", "utf8")
    let wallet = new ethers.Wallet.fromEncryptedJsonSync(
        encryptedJson,
        process.env.PRIVATE_KEY_PASSWORD
    )
    wallet = await wallet.connect(provider)
    const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf8")
    const binary = fs.readFileSync(
        "./SimpleStorage_sol_SimpleStorage.bin",
        "utf8"
    )
    const contractFactory = new ethers.ContractFactory(abi, binary, wallet)
    console.log("Please wait! Deploying... ")
    const contract = await contractFactory.deploy() //stop here! wait for contract to deploy
    await contract.deployTransaction.wait(1)
    console.log(`Contract Address: ${contract.address}`)
    const currentFavoriteNumber = await contract.retrieve()
    console.log(`Current Favorite Number = ${currentFavoriteNumber.toString()}`)
    const transactionResponse = await contract.store("7")
    const transactionReceipt = await transactionResponse.wait(1)
    const updatedFavoriteNumber = await contract.retrieve()
    console.log(`Updated Favorite Number = ${updatedFavoriteNumber.toString()}`)
}

main()
    .then(() => process.exit(0))
    .catch((error) => {
        console.error(error)
        process.exit(1)
    })

here is my .env file:

RPC_URL=https://eth-mainnet.g.alchemy.com/v2/sS1mi-JZEUU-T5a65tfcS57jzfAN6gyU
PRIVATE_KEY=*my metamask private key*

and here is my error:

I really need your help. Thank you.

You're using a rpc url for mainnet, get a rpc for goerli.

[Johnny-young]

that‘s right, thx

[zubeirarhesta]

Actually, that was Goerli RPC URL I got from alchemy. But thanks :) I decided to to change to Infura instead of alchemy and that worked. Again thank you so much for the answer.

What worked for me in similar problem with hardhat was solution from here: ethereum/solidity#13159. I added { gasLimit: 3e7 } to the affected contract function and it solved the issue.

[victorgtrrz]

I solved it by realizing that my .encryptedKey.json was not updated after shifting from Ganache to using a metamask wallet. So I updated the private key and execute the encryptKey.js snippet
