Lesson 10 getEntranceFee undefined

[SidharthK2]

I'm getting undefined in the console when I run this.

@SidharthK2 Hey! This could be due to ABI not exported to fronted side correctly! You can also copy the ABI code manually from the contract code. Go to: artifacts/contracts/CONTRACT-NAME/CONTRACT-NAME.json. Copy the ABI array (start from [ to end ])

This is from "Started HTTP and WebSocket JSON-RPC server at http://127.0.0.1:8545/"

@SidharthK2
I have the same error on server at http://127.0.0.1:8545/, can you please explain the issue ?
My chain id for hardhat local network is 31337 in my metamask, but I have the same issue that you had, entranceFee is "undefined"

@SiegfriedBz I would try making sure all package versions match the ones in the course repo. That solved a lot of my issues.

@SidharthK2 : In your updateUI function in your use effect do this :

const entranceFee = (await getEntranceFee()).toString()

Then console.log it.

Let me know if it works!

[RoboCrypter]

@SidharthK2 : Are you doing this way : const entranceFee = (await getEntranceFee()).toString() ?

[RoboCrypter]

@SidharthK2 : Just found out this mistake :

Change this line from : const raffleAddress = chainIdHex in contractAddresses ? contractAddresses[chainId][0] : null;

To this : const raffleAddress = chainId in contractAddresses ? contractAddresses[chainId][0] : null;

You have written chainIdHex , but it should be chainId as you defined in above line, Made a PR in your repo aswell!

[SidharthK2]

Still undefined, I will just start a new repo this is strange.

@SidharthK2 : I went through all of your code! but it should work by now! Strange indeed

This worked for me, thanks.

I had to change the chain id for hardhat local network from 1337 to 31337 in my metamask

I could not fix this error for a long time and figured out that there was no need to JSON.stringify the abi in your update front end deploy script.
Changing fs.writeFileSync(FRONT_END_ABI_FILE, JSON.stringify(raffle.interface.format(ethers.utils.FormatTypes.json))) to fs.writeFileSync(FRONT_END_ABI_FILE, raffle.interface.format(ethers.utils.FormatTypes.json)) fixed the issue for me.

It was adding a stringified version of json in my abi.json file when I just need the json as is.
