how to fix the err:Returned values aren't valid, did it run Out of Gas?Returned values aren't valid, did it run Out of Gas?

[Li6lac]

I get this error when I call just a 'get' function from a deployed contracted.This happens in real geth private blockchain and ropsten.I'm confused for a few weeks.Thanks for giving some suggestion.
My web3 is 1.2.6 and solcjs is 0.5.0+
the whole error message is 👍
{
err: 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.

@Li6lac Could you provide a simple example of the code (both JS and Solidity) that triggers this error so someone can reproduce the problem and debug?

It would also be helpful to know the version info of the Geth client you're using.

You might also see this error if you are not using the correct ABI for the contract you are retrieving data from

This is a really common cause of that error fwiw - perhaps you are making calls to the wrong address or not creating the contract with the correct ABI.

Thanks for reply.
For ropsten:
contract is easy enough :

pragma solidity ^0.5.0;
contract MyContract {
    string value;
    constructor() public {
        value = "myValue";
    }
    function get() public view returns(string memory ) {
        return value;
    }
    function set(string memory _value) public {
        value = _value;
    }
}

set() works well,but get() meets the error.
web3js is: use transaction to call function set() of contrac,function set()
is almost the same except for web3.eth.getTransactionCount() to send data by a tanscation.

var Tx     = require('ethereumjs-tx').Transaction
const Web3 = require('web3')
const web3 = new Web3('https://ropsten.infura.io/v3/My_INFURA_API_KEY')
//const account1 = 'my account1 address'
//const account2 = 'my account2 address'
//const pk1 = 'my pk1'
//const pk2 = 'my pk2'
//const privateKey1 = Buffer.from(pk1, 'hex')
//const privateKey2 = Buffer.from(pk2, 'hex')
const contractAddress = '0x30951343d6d80d2c94897f1a81c53cc030aef879'
const contractABI = [
    {
        "constant": false,
        "inputs": [
            {
                "internalType": "string",
                "name": "_value",
                "type": "string"
            }
        ],
        "name": "set",
        "outputs": [],
        "payable": false,
        "stateMutability": "nonpayable",
        "type": "function"
    },
    {
        "constant": true,
        "inputs": [],
        "name": "get",
        "outputs": [
            {
                "internalType": "string",
                "name": "",
                "type": "string"
            }
        ],
        "payable": false,
        "stateMutability": "view",
        "type": "function"
    },
    {
        "inputs": [],
        "payable": false,
        "stateMutability": "nonpayable",
        "type": "constructor"
    }
]
const contract = new web3.eth.Contract(contractABI, contractAddress)
contract.methods.get().call((err, val) => {
  console.log({ err, val })
})

my geth is the newest .the way for deploying and calling in geth is diffrent from above but meets the same error.What's more,there's no error in ganache-cli.And if using solidity 0.4.* ,there's no error.I think perhaps dealing the problem in ropsten will deal the other.
Thanks for replying.

@Li6lac Tried to reproduce this using the Ropsten address you linked to but everything worked and did not get an error.

Compiled the contract using solc 0.5.15 which generated this ABI (think this is identical to what you posted):

[
  {
    "inputs": [],
    "payable": false,
    "stateMutability": "nonpayable",
    "type": "constructor"
  },
  {
    "constant": true,
    "inputs": [],
    "name": "get",
    "outputs": [
      {
        "internalType": "string",
        "name": "",
        "type": "string"
      }
    ],
    "payable": false,
    "stateMutability": "view",
    "type": "function"
  },
  {
    "constant": false,
    "inputs": [
      {
        "internalType": "string",
        "name": "_value",
        "type": "string"
      }
    ],
    "name": "set",
    "outputs": [],
    "payable": false,
    "stateMutability": "nonpayable",
    "type": "function"
  }
]

Then ran:

const Web3 = require('web3');
web3 = new Web3('https://ropsten.infura.io/v3/1d13168ffb894ad28....etc');

const contractAddress = '0x30951343d6d80d2c94897f1a81c53cc030aef879';
const contract = new web3.eth.Contract(abi, contractAddress)
const val = await contract.methods.get().call();
console.log(val);

Output

ok,thank you,i get it

[NashL]

I had a similar issue and was because I set wrong the ENDPOINT for web3 in my ENV, I was working on Rinkeby Network but I copied the wrong Endpoint

From:
WEB3_ENDPOINT=https://mainnet.infura.io/v3/7c7aa534bc0a4dfe8e8198f92b281992
To:
WEB3_ENDPOINT=https://rinkeby.infura.io/v3/112sda3asdasjj33f2df3asdasf2b281992

in case helps someone else

[jeftarmascarenhas]

Can be many things, but there are two causes most common.

1. Very if you are using abi and a contract address correct.
2. Very if you are selected the correct network, for exempo, if your contract is on Rinkeby you can selected Rinkeby or if your contract is on Mainnet select the Mainnet.
