Invalid Argument Error when trying to forecast transaction

[AzizGayes]

Hello guys,

When I try to broadcast a transaction, I'm having this error:

/home/aziz/node_modules/bitcore-explorers/node_modules/bitcore-lib/lib/util/preconditions.js:14 throw new errors.InvalidArgument(argumentName, message, docsPath); ^ Invalid Argument Error at NodeError (/home/aziz/node_modules/bitcore-explorers/node_modules/bitcore-lib/lib/errors/index.js:20:41) at Object.checkArgument (/home/aziz/node_modules/bitcore-explorers/node_modules/bitcore-lib/lib/util/preconditions.js:14:13) at Insight.broadcast (/home/aziz/node_modules/bitcore-explorers/lib/insight.js:96:5) at /home/aziz/node_modules/megachain-bitcoin.js:39:12 at Request._callback (/home/aziz/node_modules/bitcore-explorers/lib/insight.js:80:12) at Request.self.callback (/home/aziz/node_modules/bitcore-explorers/node_modules/request/request.js:188:22) at emitTwo (events.js:106:13) at Request.emit (events.js:194:7) at Request.

this is my code:

var sendBTC = function (SenderPrivateKey, SenderAddress, ReceiverAddress, Amount) //adresses in string format
{ 
    SenderPrivateKey = new bitcore.PrivateKey(SenderPrivateKey,'testnet');
    ReceiverAddress = new bitcore.Address(ReceiverAddress,'testnet');
    SenderAddress = SenderPrivateKey.toAddress();
    console.log(SenderPrivateKey);
    console.log(SenderAddress);
    console.log(ReceiverAddress);

    insight.getUnspentUtxos(SenderAddress, function(err, utxos) {
        if (err) {
            console.log(err);
        } else {
            var tx = bitcore.Transaction();
            tx.from(utxos);
            tx.to(ReceiverAddress, 500000);
            tx.change(SenderAddress);
            tx.sign(SenderPrivateKey);
            tx.serialize();

            insight.broadcast(tx, function(err, txId) {
                if (err) {
                    console.log('Error!:'+err);
                } else {
                    console.log('Successfully sent: '+txId);
                }
            });

        }
    });
}

Can someone help me? thanks!

I am also having same error, if you guys @AlexanderKozhevin or @AzizGayes found any solution please let me know

[matiu]

You need to send a string to broadcast, see:

https://github.com/bitpay/bitcore-explorers/blob/master/lib/insight.js#L118

Try:

            insight.broadcast(tx.toString(), function(err, txId) {

I am getting the same error but even after using insight.broadcast(tx.toString(), function(err, txId) { The error is continuing to appear.
