contract_revert_exected Hedera智能合约

Question

Contract_revert_execuded 不确定我在做什么错，但是我正在尝试调用一个函数，并且它需要一个参数，并且我确保它是正确的，但它仍然会恢复。这是使用Hederatokenservice的Hedera-Hashgraph。

智能合约：

pragma solidity ^0.8.11;

import "./hip-206/HederaTokenService.sol";
import "./hip-206/HederaResponseCodes.sol";

contract Minting is HederaTokenService {

    address tokenAddress;
    bytes metadata;
    string baseURI = "abc";
    uint64 mintPrice;

function mintNonFungibleToken(uint64 _amount) external payable {
        bytes[] memory nftMetadatas = generateBytesArrayForHTS(
            baseURI,
            _amount
        );
        (
            int256 response,
            uint64 newTotalSupply,
        ) = HederaTokenService.mintToken(tokenAddress, _amount, metadata);

        if (response != HederaResponseCodes.SUCCESS) {
            revert("Mint Failed");
        }
    }

    // @dev Helper function which generates array of addresses required for HTSPrecompiled
    function generateAddressArrayForHTS(address _address, uint256 _items)
        internal
        pure
        returns (address[] memory _addresses)
    {
        _addresses = new address[](_items);
        for (uint256 i = 0; i < _items; i++) {
            _addresses[i] = _address;
        }
    }

    // @dev Helper function which generates array required for metadata by HTSPrecompiled
    function generateBytesArrayForHTS(bytes memory _bytes, uint256 _items)
        internal
        pure
        returns (bytes[] memory _bytesArray)
    {
        _bytesArray = new bytes[](_items);
        for (uint256 i = 0; i < _items; i++) {
            _bytesArray[i] = _bytes;
        }
    }

在JS中调用交易：

  const contractMint = await new ContractExecuteTransaction()
    .setContractId(contractId)
    .setGas(3000000)
    .setFunction(
      "mintFungibleToken",
      new ContractFunctionParameters().addUint64(1)
    )
    .setMaxTransactionFee(new Hbar(2));

另请注意，恢复通常包含有用的信息，您可以导航到hashscan.io查找智能合约的响应，例如

https：//hashscan.io/testnet/testnet/transaction/1675427464.278782297

？ message is 0x08c379a00000000000000000000000000000000000000000000000000000000000000020000000000000000000000000000000000000000000000000000000000000001b52656d697420746f6b656e20616c726561647920637265617465640000000000

with the error message starting with 0x08c379a, we know it's a string, so we can decode it

Hacky way:

• Navigate to:
• 粘贴上面的（删除0x）
• 选择ASCII以编码为字符的ASCII
• 按下转换

输出：âyy＆nbsp; 创建的汇总令牌

已在JavaScript中

const {ethers} = require("ethers");

async function main() {

    const error = "0x08c379a00000000000000000000000000000000000000000000000000000000000000020000000000000000000000000000000000000000000000000000000000000001b52656d697420746f6b656e20616c726561647920637265617465640000000000";
    const reason = ethers.utils.defaultAbiCoder.decode(
        ['string'],
        ethers.utils.hexDataSlice(error, 4)
    )
    console.log(reason);
};

void main();

看起来您正在尝试调用JS的Mintfungibletoken ，但智能合约没有mintfungibletoken函数；智能合约功能名称为mintnonfungibletoken。
