Hi,

The above question may not sound how I am working at the moment,

so I have a JSW module in backend files with the following function:

const EC = require('elliptic').ec;
import { v1 as uuidv1 } from 'uuid';
const ec = new EC('secp256k1');
import wixData from 'wix-data';
import wixUsers from 'wix-users-backend';

export function sign(dataHash) {
    console.log("sign called");
    console.log(dataHash);
    wixData.query("userWallets", wixUsers.currentUser.id)
        .find()
        .then((results) => {
 if (results.items.length > 0) {
 let wallet = results.items[0];
 const privateKey = wallet.privateKey;
 var signature = ec.keyFromPrivate(privateKey).sign(dataHash);
                console.log(signature);
 return signature;
            }
        })
}

my aim is to return the signature to a function for transactions this I provide below:

static signTransaction(transaction, senderWallet) {
        console.log("sign transaction called");
 var dataHash = ChainUtil.hash(transaction.outputs);
 var signature = sign(dataHash);
        transaction.input = {
            timestamp: Date.now(),
            amount: senderWallet.balance,
            address: senderWallet.publicKey,
            signature: signature
        }
    }

at present the sign transaction function is called and responded quicker than the function on the backend JSW file is returned so when I console.log the transaction I get the following:

update or add transaction called transaction-pool.js Line 9

0 transaction.js Line 50

Any help and assistance in getting the signature to return in the transaction would be amazing.
