Hi,

I’m getting a ‘Bad Request’ error with the below:

    [HttpGet, Route("UserToEscrow")]
    public ActionResult UserToEscrow()
    {
        //ServicePointManager.Expect100Continue = true;
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

        TransferTransaction.Version = 2;

        //  Get the 3 Accounts

        var buyerAccount = PrivateKeyAccount.CreateFromPrivateKey("<VALID KEY>", MainNetChainId);
        var sellerAccount = PrivateKeyAccount.CreateFromPrivateKey("<VALID KEY>", MainNetChainId);
        var dtp = PrivateKeyAccount.CreateFromPrivateKey("<VALID KEY>", MainNetChainId);

        //  Generate a new Escrow Account

        var newAccountSeed = PrivateKeyAccount.GenerateSeed();
        PrivateKeyAccount newAccount = PrivateKeyAccount.CreateFromSeed(newAccountSeed, MainNetChainId);
        var newAccountAddress = newAccount.Address;

        //  Set-up Node

        var node = new Node(_host);

        //  Buyer transfers Funds to Escrow Account

        TransferTransaction t = new TransferTransaction(buyerAccount.PublicKey, newAccountAddress, Assets.WAVES, 0.01m,  "User to DTP Escrow");
        t.Sign(buyerAccount);
        node.Transfer(buyerAccount, newAccountAddress, Assets.WAVES, 0.01m);

        // Sleep for 10 seconds
        Thread.Sleep(10000);

        //  Create the script for 2/3 multi-sig

        string script = "let buyerPubKey  = base58'" + Base58.Encode(buyerAccount.PublicKey) + "';" +
            "let sellerPubKey = base58'" + Base58.Encode(sellerAccount.PublicKey) + "';" +
            "let escrowPubKey = base58'" + Base58.Encode(dtp.PublicKey) + "';" +
            "let buyerSigned = if(sigVerify(tx.bodyBytes, tx.proofs[0], buyerPubKey)) then 1 else 0;" +
            "let sellerSigned = if(sigVerify(tx.bodyBytes, tx.proofs[1], sellerPubKey)) then 1 else 0;" +
            "let escrowSigned = if(sigVerify(tx.bodyBytes, tx.proofs[2], escrowPubKey)) then 1 else 0;" +
            "buyerSigned + sellerSigned + escrowSigned >= 2";

        var byteCode = node.CompileScript(script);

        //  Broadcast to network

        

        SetScriptTransaction stx = new SetScriptTransaction(newAccount.PublicKey, byteCode, MainNetChainId);
        stx.Sign(newAccount);
        var test = stx.GetJsonWithSignature();

    //	ERROR OCCURS ON THIS LINE
        node.Broadcast(stx.GetJsonWithSignature());

        // Sleep for 10 seconds
        Thread.Sleep(10000);

        //  Transfer Funds from Escrow to Seller

        TransferTransaction t1 = new TransferTransaction(newAccount.PublicKey, sellerAccount.Address, Assets.WAVES, 0.01m, "DTP Escrow to Miner");

        t1.Sign(buyerAccount);
        t1.Sign(newAccount);

        var txId = node.Broadcast(t1);

        Console.WriteLine(txId);

        return Content("Done");
    }

The error occurs here:

SetScriptTransaction stx = new SetScriptTransaction(newAccount.PublicKey, byteCode, MainNetChainId);
        stx.Sign(newAccount);
        var test = stx.GetJsonWithSignature();

    //	ERROR OCCURS ON THIS LINE
        node.Broadcast(stx.GetJsonWithSignature());

Any assistance would be much appreciated.
