Error: cannot estimate gas; transaction may fail or may require manual gas limit (LESSON 5)

[ejmorian]

I'm having trouble deploying the Simple Storage to Sepolia network using Alchemy. I'm at the end of lesson 5. where we start to use Alchemy and metamask wallet.

I keep getting this error:
"Error: cannot estimate gas; transaction may fail or may require manual gas limit " ..

If I do set a gasLimit:
"Error: insufficient funds for intrinsic transaction cost"

My metamask account has 0.2E which i think is sufficient. I can't seem to figure out what is going on. any help would be appreciated :))

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

async function main() {
    // initialise rpc and wallet
    const provider = new ethers.providers.JsonRpcProvider(process.env.RPC_URL)
    const wallet = new ethers.Wallet(process.env.PRIVATE_KEY, provider);
    console.log(process.env.RPC_URL);
    console.log(process.env.PRIVATE_KEY);

    // get abi and bytecode
    const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf8")
    const bin = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.bin", "utf8")

    // create contract
    const contract = new ethers.ContractFactory(abi, bin, wallet)
    console.log("deploying please wait...")
    // deploy contract
    const mycontract = await contract.deploy({gasLimit : 1000000})
    console.log(`contract address : ${mycontract.address}` )

    const deploymentReceipt = await mycontract.deployTransaction.wait(1)
    console.log(`Contract deployed to ${contract.address}`)
}

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

FIX: Double Check the RPC URL, I Accidentally used the Mainnet rpc url instead of sepolia.
