Lesson 6 : Value error Explorer API not set for this network.

[wilonweb]

Hello,
I make an API KEY TOKEN on etherScan.
I put my key on a .env variable
export ETHERSCAN_TOKEN=VUDMG.......

I launch the command
brownie run scripts/deploy.py --network rinkeby

I wait and if i go on etherScan rinkeby i saw my transaction.

I saw the pass verified in the console but after i got a Value Error, i don't know if is importnant or not

This is all my consol output after launch deploy.py

Waiting for https://api-rinkeby.etherscan.io/api to process contract...
Verification submitted successfully. Waiting for result...

So I'm Worried about the message

ValueError: Explorer API not set for this network
Terminating local RPC client...

Hello @NinjaTurtles-cloud
This happens when the env variables are not imported correctly, sometimes just restarting vscode should work, if you are on windows add that env variable trough windows advanced configuration, if not just copy and paste the export into the terminal before running the script.

I hope this info might help.

I got the same error but BOTH the mock and fundme said they deployed to the home ganache blockchain. As a lark I ran the below code on the rinkeby network and it deployed and verified at address 0xC7764728565BA15DCe7a973a32ad281DEf7a9e28

If there's some sort of coding error I do apologize. FOr reference as always, I'm using Mac M1 and doing all most solidity using 0.8.12

Any suggestions would be appreciated.

from brownie import FundMe, MockV3Aggregator, config, network
from scripts.helpful_scripts import get_account


def deploy_fund_me():
    account = get_account()

    if network.show_active() != "development":
        price_feed_address = config["networks"][network.show_active()][
            "eth_usd_price_feed"
        ]
    else:
        print(f"THe active network is {network.show_active()}")
        print(f"Deploying Mocks...")
        mock_aggregator = MockV3Aggregator.deploy(
            18, 2000000000000000000, {"from": account}
        )
        price_feed_address = mock_aggregator.address
        print("Mocks Deployed")

    fund_me = FundMe.deploy(price_feed_address, {"from": account}, publish_source=True)
    print(f"Contract deployed to {fund_me.address}")


def main():
    deploy_fund_me()

Could you please share your helpful_scripts file?

[JohnEMagee]

I did but it turns out I was more of an idiot than anything else. I stopped the video when it didn't work for me without watching that the same error comes up in the video and it's just a matter of dealing with the publlish_source issue. Apologies

[cromewar]

I'm glad is solved now.
