[SOLVED] Bad Request(400): Returned values aren’t valid, did it run Out of Gas?

“error”: “[C0006] Request failed, Bad Request(400): 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.”
the source code as below.

const Web3 = require('web3'); // Import Web3.js library

const express = require("express");

const Moralis = require("moralis").default;

const { EvmChain } = require("@moralisweb3/common-evm-utils");

const app = express();

const port = 3000;
const MORALIS_API_KEY = 'api-key';
const address = "0x51A12aad72f661c3B78629Af635Ba4DC233e5514"; //contract address

const chain = EvmChain.ETHEREUM;
const abi = [{
    "inputs": [],
    "name": "getLotteryRewardSize",
    "outputs": [
        "internalType": "uint256",
        "name": "",
        "type": "uint256"
    "stateMutability": "view",
    "type": "function"
async function getLotteryRewardSize() {

  try {

    const rewardSize = await Moralis.EvmApi.utils.runContractFunction({

      address: address,

      chain: chain,

      functionName: 'getLotteryRewardSize', // Function name to call

      abi: abi,


    return rewardSize; // Return the value from the function

  } catch (error) {

    throw error; 



app.get("/getLotteryRewardSize", async (req, res) => {

  try {

    // Get the reward size from the asynchronous function

    const rewardSize = await getLotteryRewardSize();

    // Send the reward size as a JSON response

    res.status(200).json({ rewardSize });

  } catch (error) {

    // Handle errors


    res.status(500).json({ error: error.message });



Hi @Dulara It looks like you have selected the chain as ethereum but I could not find your contract address on ethereum chain.

Can you correct the chain value and try again?

Yes chain should be BSC_TESTNET. Thanks
