Lesson 6 (Brownie FundMe) - Having trouble interacting with deployed FundMe contract about full-blockchain-solidity-course-py HOT 11 CLOSED

Just remember whenever you try to redeploy the contract at the first place. Remove 1337 folder and also removing it's entry in map.json in build/deployments/map.json or even better remove the whole build folder and then try redeploying it over again, with brownie run scripts/deploy.py --network ganache-local once done this means your contract has been deployed over your ganache-local blockchain and after this you can run brownie run scripts/fund_and_withdraw.py --network ganache-local over your ganache-local blockchain.

from full-blockchain-solidity-course-py.

To fix this issue, do the following:

1. Go to your deploy.py file and check the price_feed_address variable. Probably you forgot to use it here:

fund_me = FundMe.deploy(
        "0x9326BFA02ADD2366b30bacB125260Af641031331",
        {"from": account},
        publish_source=config["networks"][network.show_active()].get("verify"),
    )

2. Replace the first parameter on the deploy function with the price_feed_address variable.

That's it. Hope I could help you.

I also ran into this problem even though my FunMe.deploy was passing in the value from a variable. But in my case the problem was that I had deployed a MockV3Aggregator, then I closed Ganache. When I reopened Ganache it no longer had the MockV3Aggregator contract, but Brownie was still referencing the contract I made previously. Thus using an address that no longer existed.

Need to clean out the 1337 folder in VS Code when reopening ganache.

hmm... two thoughts.

1. Could you add all the contract and script code?
2. Could you see if this works with python 3.9?

I had the same problem, however in my code there was harcoded rinkeby contract . I removed from functions e everything went well. Try do the same if you find something similar in FundMe.sol.

hi. i have this problem as well.
i can deploy the contract but when i call the getEntranceFee function i get the same "VirtualMachineError: revert" error as above.
when deploying the contract i am using the price_feed_address.
