Out of bounds read (offset=0) error when broadcasting LTC or Dogecoin transactions.

I'm trying to send supported coins each other. Using latest version of edge-core-js and edge-currency-bitcoin, edge-currency-accountbased, I could make XRP transactions work each other. But for Dogecoin and LTC, I am getting error when broadcasting the tx data.

`const sendXrp = async () => { try { const { username, password, opt } = masterAccount; const abcContext = await getContext();

    const abcAccount = await abcContext.loginWithPassword(
        username,
        password,
        opt
    );

    console.log(`\n----- Edge Account ID ----`);
    console.log(abcAccount.id);

    const walletIds = await abcAccount.listWalletIds();
    console.log(`\n----- Wallet Ids ----`);
    console.log(walletIds);

    const walletInfo = await abcAccount.waitForCurrencyWallet(masterAccount.walletId);
    console.log(`\n----- Wallet Info ------`);
    console.log(walletInfo);

    console.log(`\n----- Wallet Address -----`);
    console.log(walletInfo.getReceiveAddress());

    const balance = await walletInfo.getBalance({currencyCode: 'LTC'});
    console.log(`\n------------------------------------- Current Balance`);
    console.log(balance);

    // start engine
    await walletInfo.startEngine();

    const tx = await walletInfo.makeSpend({
        spendTargets: [
            {
                publicAddress: 'MFktv8WkXMDh1yyYoKfZKBjb9jbSnyfdgN',
                nativeAmount: '100000'
            }
        ]
    });


    console.log(tx);

    await walletInfo.signTx(tx);

    console.log(`Broadcasting tx`);
    await walletInfo.broadcastTx(tx);
    const result = await walletInfo.saveTx(tx);

    console.log(result);

}`

It works in offline functions, signing tx data etc. But the error happens in the broadcastTx(tx) function.

I've tried Doge and LTC, but both had same errors. I tried to change amounts but no luck. Could you please advise what could be wrong or how to fix this issue?

Interesting. I see that you are running under node.js, which is not something we regularly test.

It could easily be a problem with bcoin, since I know we modified that library to run under React Native, and I don't think those modifications get picked up under node.js. However, this is not a known issue, and we don't have repo steps to debug further.
