Can't deploy contract to Rinkeby but only hardhat

[rileymross]

When I deploy the contract with deploy.js on hardhat, it automatically does hardhat but when I force it to do rinkeby by making the default network rinkeby instead of hardhat and have my .env and everything set up, it tells me

$ /home/rileymross/hh-fcc/hardhat-simple-storage-fcc/node_modules/.bin/hardhat run scripts/deploy.js

Here is my hardhat config file:

require("dotenv").config
require("@nomiclabs/hardhat-etherscan")
// This is a sample Hardhat task. To learn how to create your own go to
// https://hardhat.org/guides/create-task.html
task("accounts", "Prints the list of accounts", async (taskArgs, hre) => {
    const accounts = await hre.ethers.getSigners()

    for (const account of accounts) {
        console.log(account.address)
    }
})

const RINKEBY_RPC_URL = process.env.RINKEBY_RPC_URL

module.exports = {
    solidity: "0.8.8",

    networks: {
        rinkeby: {
            url: "RINKEBY_RPC_URL",
            account: [PRIVATE_KEY],
            chainId: 4,
        },
    },
    etherscan: {

    },
}

leave default hardhat and deploy with --network rinkeby flag

uncomment //defaultNetwork: "hardhat",

npx hardhat deploy --network rinkeby

or

yarn hardhat deploy --network rinkeby

[rileymross]

That gives me the same response.
It seems to have some problem with my RPC URL for some reason.

[mattjaf]

you dont need quotes around "RINKEBY_RPC_URL"

and its accounts: [PRIVATE_KEY], not account: [PRIVATE_KEY],

[rileymross]

Found that both of those were untrue on my own. Not everything is exactly as the guide says.
But this all seems to stem form how alchemy refuses to detect my metamask or anything associated with rinkeby, thus I suspect there's something wrong with the RPC URL they give me. I don't understand what it going on with this. It's some problem with the way it connects to the URL and it even gave me problems when I tried connecting it to Ganache and other testnets.

[mattjaf]

why would you connect your alchemy RPC url to ganache?

They have options on alchemy for other networks...

rinkeby is for rinkeby

[rileymross]

That's not what I said. Ganache has nothing to do with it, I was just using that as an example.

@rileymross you have commented out the default network that was hardhat. So if you comment on the default network it will still be hardhat by default.

The error is saying that it is a Type error in the URL, you should try this:

module.exports = {
    solidity: "0.8.8",
    defaultNetwork: "rinkeby",
    networks: {
        rinkeby: {
            url: process.env.RINKEBY_RPC_URL,
            accounts: [process.env.PRIVATE_KEY],
            chainId: 4,
        },
    },
    etherscan: {
        apiKey: process.env.ETHERSCAN_API_KEY,
    },
}
