错误：返回的值无效，是否耗尽 Gas？在 web3.min.js 中

问题描述

我已经部署了我的智能合约，我的交易也在元掩码中完成，但是当我尝试通过调用智能合约的函数来显示我的结果时，我已经检查了数据类型，但我收到了这样的错误

Error: Returned values aren't valid,did it run Out of Gas?
    at i.decodeParameters (web3.min.js:10290)
    at o._decodeMethodReturn (web3.min.js:12156)
    at _.outputFormatter (web3.min.js:12196)
    at _.formatOutput (web3.min.js:7396)
    at u (web3.min.js:7437)
    at web3.min.js:8026
    at s._handle (inpage.js:17) undefined

我不知道为什么它没有在 web3.min.js 中解码信息，而我的 js 代码是

if (typeof web3 !== 'undefined') {
        web3 = new Web3(web3.currentProvider);
    } else {
        web3 = new Web3(new Web3.providers.HttpProvider('http://localhost:7545'));
    }

    // Set Contract Abi
    var contractAbi = [{
        "anonymous": false,"inputs": [{
            "indexed": true,"internalType": "address","name": "account","type": "address"
        }],"name": "distributorAdded","type": "event"
    },{
        "anonymous": false,"name": "distributorRemoved","inputs": [{
            "indexed": false,"internalType": "string","name": "_batchno","type": "string"
        }],"name": "Made","name": "ManufacturerAdded","name": "ManufacturerRemoved","name": "Packed","name": "Sold","name": "UserAdded","name": "UserRemoved",{
        "constant": false,"inputs": [{
            "internalType": "address","name": "adddistributor","outputs": [],"payable": false,"stateMutability": "nonpayable","type": "function"
    },"name": "addManufacturer","name": "addUser",{
        "constant": true,"inputs": [{
            "internalType": "string","name": "fetchMedicineBufferOne","outputs": [{
            "internalType": "string","name": "batchno","type": "string"
        },{
            "internalType": "string","name": "medicineName",{
            "internalType": "address","name": "ownerID","type": "address"
        },"name": "originManufacturerID","name": "dosage",{
            "internalType": "enum main.State","name": "medicinestate","type": "uint8"
        }],"stateMutability": "view","name": "fetchMedicineBufferTwo","name": "FactoryName","name": "mfgdate","name": "expdate","name": "distributorID","name": "userID","name": "isdistributor","outputs": [{
            "internalType": "bool","name": "","type": "bool"
        }],"name": "isManufacturer","name": "isUser","name": "_medicineName","name": "_dosage","name": "_originManufacturerID","name": "_ownerID","name": "_FactoryName","name": "_mfgdate","name": "_expdate","type": "uint8"
        },"name": "_distributorID","name": "_userID","name": "makeMedicine","name": "packMedicine","name": "receiveMedicine","inputs": [],"name": "renouncedistributor","name": "renounceManufacturer","name": "renounceUser","type": "function"
    }]; // Add Your Contract ABI here!!!

    // Set Contract Address
    var contractAddress = '0xd9145CCE52D386f254917e481eB44e9943F39138'; // Add Your Contract address here!!!

    // Set the Contract
    var contract = new web3.eth.Contract(contractAbi,contractAddress);
    $('form').on('submit',function(event) {
        event.preventDefault();
        batchno = $("#batchno").val();
        console.log(batchno)
            //display the Medicine
        contract.methods.fetchMedicineBufferOne(batchno).call(function(err,result) {
            console.log(err,result)
            $('#ftc-medicine').html(result);

        });
    });

我的智能合约功能是

function fetchMedicineBufferOne(string memory _batchno) public view returns 
  (
    string memory batchno,//the primary key batchno 
    string memory  medicineName,//Medicine name
    address ownerID,address originManufacturerID,string memory dosage,State medicinestate
    ) 
  }
return 
  (
    medicines[_batchno].batchno,medicines[_batchno].medicineName,medicines[_batchno].ownerID,medicines[_batchno].originManufacturerID,medicines[_batchno].dosage,medicines[_batchno].medicinestate
    );
}

创建了药物数组并将值存储在此函数中

function makeMedicine(string memory _batchno,string memory _medicineName,string memory _dosage,address  _originManufacturerID,address _ownerID,string memory _FactoryName,string memory _mfgdate,string memory _expdate,State,address _distributorID,address _userID) public
  
  onlyManufacturer

  {
    // Add the new medicine as part of medicines
    Medicine memory makeMedicine = Medicine({
      batchno:_batchno,medicineName:_medicineName,dosage:_dosage,originManufacturerID:_originManufacturerID,// Metamask-Ethereum address of the Manufacturer
      ownerID:_ownerID,// Metamask-Ethereum address of the current owner as the medicine moves through 3 stages
      FactoryName:_FactoryName,// Manufacturer Name
      mfgdate:_mfgdate,//mfgdate
      expdate:_expdate,//expdate
      medicinestate: State.Made,distributorID: _distributorID,userID: _userID

      });
    medicines[_batchno] = makeMedicine;
    medicines[_batchno].medicinestate = State.Made;

我在 ganache 中编译和部署了我的合约，我也在 remix 中进行了部署，其中函数运行正常我在哪里出错？
