I'm not sure whats going on. This is the last piece of the puzzle for me

@VaderUri I'm not sure whats going on. I think everything is setup.

@HashLips any insight?

same issue here, deployed on polygon testnet

Make sure you put in your contract abi. I created a new abi file "myABI.json" and copied my contract-specific abi to that file. I then went to "src > redux >blockchain > blockchainActions.js" and updated the abi location.

export const connect = () => {
  return async (dispatch) => {
    dispatch(connectRequest());
    const abiResponse = await fetch("/config/myABI.json", {

Also, my mint call in my contract is "mintSale", by default, in this minting dapp it was set to "mint" so check that in the App.js

 const claimNFTs = () => {
    let cost = CONFIG.WEI_COST;
    let gasLimit = CONFIG.GAS_LIMIT;
    let totalCostWei = String(cost * mintAmount);
    let totalGasLimit = String(gasLimit * mintAmount);
    console.log("Cost: ", totalCostWei);
    console.log("Gas limit: ", totalGasLimit);
    setFeedback(`Minting your ${CONFIG.NFT_NAME} NFT...`);
    setClaimingNft(true);
    blockchain.smartContract.methods
      .mintSale(mintAmount)
      .send({
        gasLimit: String(totalGasLimit),
        to: CONFIG.CONTRACT_ADDRESS,
        from: blockchain.account,
        value: totalCostWei,

Same error here, maybe it is caused by an change in the web3 lib?

from hashlips_nft_minting_dapp.

@rcpilotp51 I fixed it, it has to do with your ABI file. If i put the default ABI file in the folder it fixes the problem. The methods .mint() and for example .getTotalSupply() missed in my ABI file so thats why it keeps crashing.

from hashlips_nft_minting_dapp.

Have you found the fix to this issue?

I am seeing people saying the ABI but mine says safeMint so i changed the ".mint" to ".safeMint" and it still is not working. or is giving me another error saying invalid address, or saying it received two parameters but was expecting one.

Any help is appreciated,
thank you.

Has anyone managed to fix this ?
