I am attempting to send a transaction in the Ethereum Sepolia testnet, but I keep getting gas fees errors. I have had the transaction signed and sent using the web3 library.

const { Web3 } = require('web3');
const web3 = new Web3('https://eth-sepolia.g.alchemy.com/v2/9aHCL7I90Xo_YSRD3P1PxkyMEANMyWl7');
const marketABI = require('./abi/Market.json')

let dateInWeek = new Date();
dateInWeek.setDate(dateInWeek.getDate() + 7);
const deadline = Math.floor(dateInWeek.getTime() / 1000);

let tempContract = new web3_.eth.Contract(marketABI, '0xD72C08f47188a41E9182F793ed6d46192db61D9A')

const gasSuggestion = await web3.eth.getGasPrice();

const tx = {
from: '0xc768B39DBcBCCfD6dECae24b0a591e78BEA3382F',
to: '0xD72C08f47188a41E9182F793ed6d46192db61D9A',
gasPrice: web3.utils.toHex(gasSuggestion),
maxFeesPerGas: web3.utils.toHex(gasSuggestion),
gas: web3.utils.toHex(gasSuggestion),
data: tempContract.methods.createMarket('Title placeholder', 'description placeholder', 'crypto','http://google.com',deadline).encodeABI()}

const sign = await web3.eth.accounts.signTransaction(tx, privateKey);
web3.eth.sendSignedTransaction(sign.rawTransaction);

I get the following error:

    _events: Events <[Object: null prototype] {}> {},
