× Error: Invalid number of parameters for "mint". Got 1 expected 2! about hashlips_nft_minting_dapp HOT 12 OPEN

I get "× Error: Invalid number of parameters for "mint". Got 1 expected 2!" error when trying to mint one on Rinkeby network

from hashlips_nft_minting_dapp.

Looks like it is something with this line: blockchain.smartContract.methods .mint(mintAmount)

from hashlips_nft_minting_dapp.

Same happening with me

from hashlips_nft_minting_dapp.

Note: this dapp is designed to work with the intended NFT smart contract, that only takes one parameter in the mint function "mintAmount". But you can change that in the App.js file if you need to use a smart contract that takes 2 params.

change the line to

.mint(blockchain.account, mintAmount)

from hashlips_nft_minting_dapp.

Hello, I had this issue and changed the line which now allows for metamask to pop up and confirm the transaction.
However, the transaction always fails on rinkeby and the logs on the contract show failed too. The dapp then says sorry something went wrong. I cannot seem to figure out how to get the transactions to go through successfully.

Thanks!

double check you have the correct abi loaded for your contract

from hashlips_nft_minting_dapp.

Ok, thank you, so I forgot to paste in my abi. I did that now I get this error:

Here is my code from that section:

Thanks for the help. I am self teaching
abi.txt

I also attached my abi

hrm looks similar to mine. ive made some changes as it wasnt charging the user the correct amount

  const claimNFTs = () => {
    let cost = CONFIG.WEI_COST;
    let gasLimit = CONFIG.GAS_LIMIT;
    let totalCostWei = String(cost * mintAmount);
    let totalGasLimit = String(gasLimit * mintAmount);
    let costValue = blockchain.web3.utils.toWei((CONFIG.DISPLAY_COST * mintAmount).toString(), "ether")
    console.log("Cost: ", totalCostWei);
    console.log("Gas limit: ", totalGasLimit);
    setFeedback(`Minting your ${CONFIG.NFT_NAME}...`);
    setClaimingNft(true);
    blockchain.smartContract.methods
      .mint(blockchain.account, mintAmount)
      .send({
        gasLimit: String(totalGasLimit),
        to: CONFIG.CONTRACT_ADDRESS,
        from: blockchain.account,
        value: costValue,
      })
      .once("error", (err) => {
        console.log(err);
        setFeedback("Sorry, something went wrong please try again later.");
        setClaimingNft(false);
      })
      .then((receipt) => {
        console.log(receipt);
        setFeedback(
          `WOW, You have a ${CONFIG.NFT_NAME} citizen! go visit Opensea.io to view it.`
        );
        setClaimingNft(false);
        dispatch(fetchData(blockchain.account));
      });
  };

I got it to the point where it tries to mint but the transaction always fails :(

Example transaction: 0x25ab6b1bb5a23d24da5bd657e681f24808243b307345e7cf9b87301ed4603d18

from hashlips_nft_minting_dapp.

What worked for me:
Modify the mint function in the contract to add an address as its first parameter (I called it recipient) and leave the uint256 mintAmount as the second. It's a bit of a kludge, but you could argue that it's now more flexible, as you could then mint an NFT for someone else. This is all abstracted away behind the Minting Dapp, however, and you can simply use blockchain.account (current user) as the first parameter to mint within App.js.
More to the point, Metamask pops up now and there are no errors when buying an NFT.

from hashlips_nft_minting_dapp.

Had the same issue and I figured out that its because my smart contract doesn't take an input for minting while the DAPP is trying to send an input, as the error reads for some got 1 expected 0, got 2 expected 0, got 2 expect 1 and so on... so I since mine doesn't take an input from user, its a straight forward mint. I removed the parameters passed within and made the function .mint()
Use it based on ur contracts mint function and it should work!
Cheers!!!

Hey man this code above will that stop people getting my nft for free, for some reason people can mint direct on contract and not pay minting cost
