Lesson 6 : List index out of range (MacOS Catalina 10.15.7)

[JamiDEV]

Lesson 6 has been really beating me down.

another major issue, for the life of me I can't understand why, I've checked the code and it all seems correct what am I missing? Mind you when I deploy without targeting a network it runs just fine.

the error:

i'm looking for the for brownie/network/contract.py file but can't find it, would this be somewhere else? I do understand the error, I've tried to change the fund me parameter from -1 to 0, but nothing works.

Hello @JamiDEV when brownie is looking for FundMe[-1] it means is trying to get the json info of that contract after the last deployment, so the problem might be to due deployment, did you deploy FundMe.sol contract after trying to access to it?

[cromewar]

is a parameter you can add on brownie after {"from": account, }also I noticed the error is saying you need to spend more eth, so make sure your functions are something like this:

def fund():
    fund_me = FundMe[-1]
    account = get_account()
    entrance_fee = fund_me.getEntranceFee()
    print(entrance_fee)
    print(f"The current entry fee is {entrance_fee}")
    print("Funding")
    fund_me.fund({"from": account, "value": entrance_fee})

on the contract

  function fund() public payable {
       uint256 mimimumUSD = 50 * 10**18;
       require(
           getConversionRate(msg.value) >= mimimumUSD,
           "You need to spend more ETH!"
       );
       addressToAmountFunded[msg.sender] += msg.value;
       funders.push(msg.sender);
   }

also you can add a little more on the entrance fee to be sure you are sending the correct amount like:

fund_me.fund({"from": account, "value": entrance_fee+ addiotionalAmountYouwant})

Okay. I think I'm just gonna move on, I understand the issue but now I'm spending more time troubleshooting than learning. I've learned a great deal though.

[cromewar]

Feel free to make any other question.

[JamiDEV]

thank you brother, you are an immense help.

[JamiDEV]

Heads up, your suggestion for adding more money to the entrance fee worked. Patrick had it later in the tutorial.
