LibraryError: RPC: Invalid params: {"reason":"missing field `simulation_flags`}

Describe the bug I try to use Starknet-js using Javascript on Visual Studio code. I want to set a number in my contract using Invoke, but I keep getting the error:

file:///Users/egeaybars123/Desktop/simple_storage_sdk/node_modules/starknet/dist/index.mjs:2655 throw new LibraryError( ^

To Reproduce You can copy and paste my code to reproduce the problem:

import { Account, RpcProvider, json, Contract } from 'starknet';
import fs from 'fs';
import * as dotenv from 'dotenv';
dotenv.config();

const privateKey = process.env.PRIVATE_KEY;
const ApiKey = process.env.API_KEY;
//https://starknet-sepolia.public.blastapi.io
const provider = new RpcProvider({ nodeUrl: 'https://starknet-sepolia.g.alchemy.com/v2/' + ApiKey });

const accountAddress = '0x067981c7F9f55BCbdD4e0d0a9C5BBCeA77dAcB42cccbf13554A847d6353F728e';

const account = new Account(provider, accountAddress, privateKey, "1");

const compiledContractAbi = json.parse(
    fs.readFileSync('./abi.json').toString('ascii')
);

const contractAddress = '0x01bb7d67375782ab08178b444dbda2b0c1c9ff4469c421124f54e1d8257f2e97';
const storageContract = new Contract(compiledContractAbi.abi, contractAddress, provider);

storageContract.connect(account);

const getData = await storageContract.get();
console.log('Stored_data before set():', getData.toString());

const myCall = storageContract.populate('set', [15]);
const res = await storageContract.set(myCall.calldata);
await provider.waitForTransaction(res.transaction_hash);

I fixed the problem. I was following along the Starknet-js documentation, and I found out that I needed to change the version to "Next" in the documentation. Then, I found out that rpc version was v0.6, so I bumped the Starknet-js version to 6.6.6. Then, the problem was fixed, and I could invoke a function in my contract.
