Error: Transaction has been reverted by the EVM

Question

I am trying to call the following solidity method from my smart contract in javascript:

address[] public investors;

 function addInvestor(address investor) public {
        investors.push(investor);
    }


========================Javascript code===================

const Web3 = require('web3')
const web3 = new Web3('https://goerli.infura.io/v3/c21338274bfc4a2ca6d4cb88789ed820');
const tokenContractABI = require('./abi.json');
const tokenContractAddress = '0x5fB7bFD1ac3804934E9Dbc32398C330B69826894'; 
const investor = '0xFBBd1c24C8e68831bD8c3e82b305df8fb70494a6';
const privateKey = '9XXX';

const tokenContract = new web3.eth.Contract(tokenContractABI, tokenContractAddress);


async function callAddInvestor() {
    try {
        const sender = web3.eth.accounts.privateKeyToAccount(privateKey);
        const gasLimit = 22000; 
        const nonce = await web3.eth.getTransactionCount(sender.address);

        const functionCall = tokenContract.methods.addInvestor(investor); 
        const encodedABI = functionCall.encodeABI();

        const transactionObject = {
            to: '0x5fB7bFD1ac3804934E9Dbc32398C330B69826894',
            gas: gasLimit,
            gasPrice: await web3.eth.getGasPrice(),
            data: encodedABI,
            nonce: nonce,
            chainId: 5
        };

        const signedTransaction = await sender.signTransaction(transactionObject);
        const receipt = await web3.eth.sendSignedTransaction(signedTransaction.rawTransaction);
        const investors = await tokenContract.methods.investors().call();
        console.log('Get investors :', investors);
        console.log('Transaction receipt:', receipt);
    } catch (err) {
        console.error(err);
    }
}

callAddInvestor();

I am getting the error:
