CONTRACT_REVERT_EXECUTED Hedera 智能合约

Question

CONTRACT_REVERT_EXECUTED 不知道我做错了什么，但我正在尝试调用一个函数，它接受一个参数，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中调用事务：

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

错误消息以 开头0x08c379a，我们知道它是一个字符串，因此我们可以对其进行解码
