事務在混音中工作，但沒有從 dapp 出錯

我有一個部署其他契約實例的主契約。

pragma solidity ^0.5.0;
pragma experimental ABIEncoderV2;

contract DataEntityContract {


   DataEntity DE;

   constructor(string memory _name,string[] memory _relatedEntities, string memory _date, string memory _fileName, string memory _annotations) public
   {
       DE = DataEntity(_name, 'URN', _fileName, new string[](0), _relatedEntities, 'references', _annotations, msg.sender, _date);
   }

   struct DataEntity {
       //Event notifications;
       string dataEntityName;
       string rawFileURN;
       string fileName;
       string[] nameChangeHistory;
       string[] sources;
       string references;
       string annotations;
       address createdUpdateBy;
       string when;
   }

   function editDE() public {
       DE.annotations = "edited";
   }

   function getAnnotations() public view returns(string memory) {
       return (DE.annotations);
   }

}

contract FlattenedDEC
{
   address owner;
   string public name;
   mapping (string => address) dataEntities;
   string[] public dataEntityNames;
   uint count = 0;
   uint public DataEntitiesCount = 0;
   mapping(uint => Lineage) public lineageInfo;
   mapping(uint => DE) public DataEntities;

   event DataEntityEdited(
       string name,
       string comments,
       address editedBy
   );

   constructor() public
   {
       name = "DataEntityCatalogue Master Contract";
       owner = msg.sender;
   }

   function createNewDataEntity(string memory _name, string[] memory _dataEntities, string memory _date, string memory _fileName, string memory _annotations) public returns(address _new){
       DataEntityContract instance = new DataEntityContract(_name,_dataEntities, _date, _fileName, _annotations);
       return address(instance);
   }

   function editDE(string memory _name) public{
       DataEntityContract de = DataEntityContract(dataEntities[_name]);
       de.editDE();
       emit DataEntityEdited(_name, "edited", msg.sender);
   }

現在，當我嘗試從我的 dapp 呼叫 FlattenedDEC 甚至 DataEntityContract 中的 editDE 方法時，我得到了一個 jsonrpc 錯誤，但是當我從 remix 呼叫相同的方法時，一切正常。

這是我的反應js程式碼：

async editDataEntity(name){
   const web3 = window.web3;
   const networkId = await web3.eth.net.getId();
   const networkData = await FlattenedDEC.networks[networkId];
   const contract = web3.eth.Contract(FlattenedDEC.abi, networkData.address);
   contract.methods.editDE().send({from: this.state.account})
   .on('error',(error) => {
     console.log("error: ", error);
   })
   .on('transactionHash', () => {
     console.log("edited");
   });
 }

這是我得到的錯誤：

MetaMask - RPC Error: Error: [ethjs-rpc] rpc error with payload 
{"id":6402969023659,"jsonrpc":"2.0","params":
["0xf9010e8203dc85746a528800836170d494ca9a565e46004c9e5f9b2ac2b4ca83d61814c20180b

9fe3a97a44c91451632abb02789e10612"],
"method":"eth_sendRawTransaction"}

所以，

事實證明，每當發生此錯誤時，都是因為我們正在向合約發送一些奇怪的數據。因此，就我而言，我沒有發送正確的參數，而是發送了一個空名稱。這需要大量調試才能得出這個結論。這實際上為我解決了更多問題。

因此，資訊是每當有人收到此錯誤時，請檢查傳遞給合約方法的值。
