查看功能错误：返回的值ern＆＃x27; t有效，它用完了气体吗？

我正在调用Ganache中部署的智能合约中的方法。其他方法工作正常，但是视图功能返回错误。

这是固体中的视图函数：

mapping (address => Count) private counts;

function getCounts (address user)
public
view
returns(uint a, uint b, uint total){
    return(counts[user].a, counts[user].b, counts[user].total);
}

我称之为方法：

web3.eth.getAccounts(function(error, accounts){
    if(error){
        console.log(error);
    }
    var account = accounts[0];

    contracts.SampleContract.deployed().then(function(instance){
        credsInstance = instance;
        
        return credsInstance.getCounts.call(account, {from: account});
    }).then(function(creds){
        console.log(creds[0]);
    }).catch(function(error){
        console.log(error.message);
    });
});

这是getCounts的ABI，

{
  "inputs": [
    {
      "internalType": "address",
      "name": "user",
      "type": "address"
    }
  ],
  "name": "getCounts",
  "outputs": [
    {
      "internalType": "uint256",
      "name": "academic",
      "type": "uint256"
    },
    {
      "internalType": "uint256",
      "name": "workExp",
      "type": "uint256"
    },
    {
      "internalType": "uint256",
      "name": "total",
      "type": "uint256"
    }
  ],
  "stateMutability": "view",
  "type": "function",
  "constant": true
},

我会遇到此错误：

返回的值无效，它用完了气体吗？如果您不使用正确的合同数据，请从不存在的块号中请求数据或查询未完全同步的节点的数据，也可能会看到此错误。

我也有最新的Web3。我该如何解决？

编辑：

要初始化合同，我使用了松露的官方文件。这是代码：

var contract = require('@truffle/contract');
$.getJSON('../build/contracts/SampleContract.json', function(data) {
    // Get the necessary contract artifact file and instantiate it with @truffle/contract
    var CredsArtifact = data;
    contracts.SampleContract = TruffleContract(CredsArtifact);
  
    // Set the provider for our contract
    contracts.SampleContract.setProvider(web3Provider);
});

原文

I'm calling the methods in the deployed smart contracts in Ganache. Other methods are working fine, but the view functions returns an error.

Here's the view function in Solidity:

mapping (address => Count) private counts;

function getCounts (address user)
public
view
returns(uint a, uint b, uint total){
    return(counts[user].a, counts[user].b, counts[user].total);
}

Here's how I call the method:

web3.eth.getAccounts(function(error, accounts){
    if(error){
        console.log(error);
    }
    var account = accounts[0];

    contracts.SampleContract.deployed().then(function(instance){
        credsInstance = instance;
        
        return credsInstance.getCounts.call(account, {from: account});
    }).then(function(creds){
        console.log(creds[0]);
    }).catch(function(error){
        console.log(error.message);
    });
});

Here's the ABI of getCounts

{
  "inputs": [
    {
      "internalType": "address",
      "name": "user",
      "type": "address"
    }
  ],
  "name": "getCounts",
  "outputs": [
    {
      "internalType": "uint256",
      "name": "academic",
      "type": "uint256"
    },
    {
      "internalType": "uint256",
      "name": "workExp",
      "type": "uint256"
    },
    {
      "internalType": "uint256",
      "name": "total",
      "type": "uint256"
    }
  ],
  "stateMutability": "view",
  "type": "function",
  "constant": true
},

I'm getting this error:

Returned values aren't valid, did it run Out of Gas? You might also see this error if you are not using the correct ABI for the contract you are retrieving data from, requesting data from a block number that does not exist, or querying a node which is not fully synced.

I also have the latest web3. How can I fix this?

Edit:

to initialize the contract I used Truffle's official documentation. Here's the code:

var contract = require('@truffle/contract');
$.getJSON('../build/contracts/SampleContract.json', function(data) {
    // Get the necessary contract artifact file and instantiate it with @truffle/contract
    var CredsArtifact = data;
    contracts.SampleContract = TruffleContract(CredsArtifact);
  
    // Set the provider for our contract
    contracts.SampleContract.setProvider(web3Provider);
});
