Lesson 9: "Network Rinkeby doesn't exist"

[DorianDaSilva]

As a solution for the issue #1088 hasn't been found after 1 week of research & collab, I proceeded to cloning the course repo for the lesson hoping to be able to run staging test properly but instead I am getting the following error:

Error HH100: Network rinkeby doesn't exist

I am wondering if Alchemy's Rinkeby is deprecated since it is not being called & suspect this may be the reason for the "timeout error" in the issue linked above.

So far, I have created a new subscription with a new consumer and used the consumer address to register upkeep but errors persist.

Should I switch to a different testnet or try a different RPC provider?

Thank you!

Try a different chain: (I used Rinkeby and Goerli on Alchemy - both worked fine) if it does not work still, send the repo and I will look into it

Hello I just tried my first deployment but it didn't work.... I tried adding the testnet eth to my metamask but it keeps giving me an error that my account has been funded. Please what should I do?

[DorianDaSilva]

@krakxn I was thinking of doing that. Trying Goerli or Ropsten to see if this is causing the issue.

Debug Repo is here: https://github.com/DorianDaSilva/RaffleStagingDebug

My set up for VRF & Keepers below

I used consumer address to create upkeep but I am not sure if it is correct.

Help is very much appreciated as it has been an ongoing issue for the past week or so. thank you!

Did they work? Goerli and Rinkeby are working fine for me.

Is .env fine? Maybe typos?

Did you try these steps? https://stackoverflow.com/questions/71147813/hardhat-config-error-hh100-network-goerli-doesnt-exist

[DorianDaSilva]

@krakxn Still getting the same error with rinkeby & none of the steps described above worked on the course repo. Going through the entire lesson once again to try to figure out the issue or what I missed.

.env is fine now but from now on all keys will be encrypted for production & testnet to prevent this to happen again

I would suggest moving on honestly, but please grasp the concept before doing so. Why I am recommending this? It is to avoid wastage of time - which could be better utilized self-learning and practicing the concepts in the course. Because after all, this is still a course - it is the general idea which matters, and employing them to use.

Rinkeby on alchemy is working fine.The only networks about to be depricated are kovan and ropsten.I commented out my networks in hardhat-config and got the same error as you .I think you might be missing this in your hardhat-config .

 networks: {
        rinkeby: {
            url: RINKEBY_RPC_URL,
            accounts: [PRIVATE_KEY],
            chainId: 4,
            blockConfirmations: 6,
        },
    },

The module.exports in hardhat-config should look something like this :

module.exports = {
    
    solidity: {
        compilers: [{ version: "0.8.8" }, { version: "0.6.6" }],
    },
    defaultNetwork: "hardhat",
    networks: {
        rinkeby: {
            url: RINKEBY_RPC_URL,
            accounts: [PRIVATE_KEY],
            chainId: 4,
            blockConfirmations: 6,
        },
    },
    gasReporter: {
        enabled: true,
        outputFile: "gas-report.txt",
        noColors: true,
        currency: "USD",
        coinmarketcap: COINMARKETCAP_API_KEY,
        token: "ETH",
    },
    etherscan: {
        apiKey: ETHERSCAN_API_KEY,
    },
    namedAccounts: {
        deployer: {
            default: 0,
        },
        player: {
            default: 1,
        },
    },
}

@IANGECHUKI176 I doubled check hardhat.config on both my own contract and course repo and it all seems in order but still getting the error.

@IANGECHUKI176 I faced the same error, resolved it later but after running the staging test it says RINKEBY_RPC_URL not defined even though I have defined it in my .env file, any idea what could be done?
