Error Sending Transaction #6

werewolfe · 2019-03-18T22:20:29Z

I'm having trouble sending a transaction. I've been following the errors, but not sure where the problem is.

Here is the current error in the console:

Unable to send Transaction! Error: Unable to build Transaction 
Error: No Inputs or Outputs selected! Fail! at TransactionBuilder.sendTX (TransactionBuilder.js:642)

Here is my current transaction code:

sendPayment(){
    let address = new HDMW.Address(this.digibyte.seed, HDMW.Networks.digibyte, false);
    this.myWallet.sendPayment({
      from: address,
      to: { "DU22gCjXbV8R43PPJXb8ichDfEVQdHJsaa": 1 },
      coin: "digibyte",
    }).then(function(txid){
      this.txid = txid;
      console.log("Successfully sent Transaction! " + this.txid);
    }).catch(function(error){
      console.error("Unable to send Transaction!", error)
    })
 }

I've tried different versions of this with the same error:

sendPayment(){
    this.myWallet.sendPayment({
      to: { "DU22gCjXbV8R43PPJXb8ichDfEVQdHJsaa": 1 },
      coin: "digibyte",
    }).then(function(txid){
      this.txid = txid;
      console.log("Successfully sent Transaction! " + this.txid);
    }).catch(function(error){
      console.error("Unable to send Transaction!", error)
    })
  }

I guess I'm not sure how to pass the options details correctly.

The text was updated successfully, but these errors were encountered:

So it looks like it's not able to find the inputs it needs to build the transaction. This could be caused by a couple of things, but I don't think it's your code. Because I cannot test can you do this for me? Go into your node_modules/oip-hdmw/lib/TransactionBuilder.js at line 495 and log a few variables for me please. The code should look like this:

}, {
		key: 'buildTX',
		value: async function buildTX(manual_selected) {
			var _this2 = this;

			var selected = manual_selected;

			if (!selected) {
				try {
					selected = await this.buildInputsAndOutputs();
				} catch (e) {
					throw new Error("Unable to select inputs and outputs \n" + e);
				}
			}

			this.selected = selected;

			var inputs = selected.inputs;
			var outputs = selected.outputs;
			var fee = selected.fee;

			// inputs and outputs will be undefined if no solution was found
			if (!inputs || !outputs) {
				throw new Error("No Inputs or Outputs selected! Fail!");
			}

Log selected before and after the if statement
Then log inputs, outputs, and fee and we'll go from there!

werewolfe · 2019-03-18T22:48:02Z

Here are the logs:

console.log(selected) before if: -> TransactionBuilder.js:500 undefined      
console.log(selected) after if: -> TransactionBuilder.js:508 {fee: 18816} fee: 18816__proto__: Object
console.log(inputs) -> TransactionBuilder.js:512 undefined
console.log(outputs) -> TransactionBuilder.js:514 undefined
console.log(fee) -> TransactionBuilder.js:516 18816

orpheus · 2019-03-19T01:08:23Z

okay, now at line 388 under this function:

if (!utxos) {
	try {
		utxos = await this.getUnspents();
	} catch (e) {
		throw new Error("Unable to get Unspents for Addresses \n" + e);
	}
}

log utxos

Pretty much going to have to keep going back until we find which variable isn't returning correctly. Or if you want to publish your repo, I can clone and take a look at it myself.

But under utxos, look at the major variables being declared and see which one returns null/undefined. When we do, I can make a change and add better error handling.

werewolfe · 2019-03-19T02:00:02Z

Here is the utxos log. I think we're getting somewhere.

I did send 1 DGB to the address to test, so it looks like it is there.

orpheus · 2019-03-19T15:35:36Z

alright, now log selected under this line:
var selected = (0, _coinselect2.default)(utxosNoUnconfirmed, targets, Math.ceil(this.coin.feePerByte), extraBytesLength);

werewolfe · 2019-03-19T16:17:07Z

Got the fee

TransactionBuilder.js:427 console.log(selected); -> {fee: 18816} fee: 18816__proto__: Object

orpheus · 2019-03-19T19:44:55Z

log these variables utxosNoUnconfirmed, targets, Math.ceil(this.coin.feePerByte), extraBytesLength
before var selected = ...

Wondering if it's a problem with the coinselect function

werewolfe · 2019-03-19T23:05:42Z

console.log(utxosNoUnconfirmed); 425

[{…}]

console.log(Math.ceil(this.coin.feePerByte)); 427

console.log(extraBytesLength); 428

At least they each have a value.

bitspill · 2019-03-19T23:10:20Z

value: undefined seems highly suspect and should refer to the 1 DGB that's contained within d59b065a32ffccfed897b1fd9b5a42366b1471022213c66d82da486e2c797396:0

I didn't catch that, interesting.

orpheus · 2019-03-21T15:25:21Z

I think I might have an idea. When you logged utxos it was this:

[{…}]
0:
address: "DNf2iFGDwfUPnSbcY8KRZBjHdTgzgrrAYm"
amount: 1
confirmations: 6
confirmationsFromCache: true
scriptPubKey: "76a914c0236c01b74bd84a8a269696f74d67b179c904cd88ac"
ts: 1552630412
txid: "d59b065a32ffccfed897b1fd9b5a42366b1471022213c66d82da486e2c797396"
vout: 0
__proto__: Object
length: 1
__proto__: Array(0)

but then right after it gets back the utxos, it tries to format them like this:

var formattedUtxos = utxos.map((utxo) => {
			return {
				address: utxo.address,
				txId: utxo.txid,
				vout: utxo.vout,
				scriptPubKey: utxo.scriptPubKey,
				value: utxo.satoshis,
				confirmations: utxo.confirmations
			}
		})

value is looking for utxo.satoshis but in the utxos, there's no satoshiskey.

Can you verify this?

orpheus · 2019-03-21T15:28:59Z

if you look at the documentation here, there is both amount and satoshis. So did satoshis come back undefined or was it not returned at all?

bitspill · 2019-03-21T17:44:39Z

Looks like https://digiexplorer.info is running Insight API v0.2.12 whereas FLO is currently running Insight API v5.0.0-beta.72

The DGB API doesn't return a satoshi value https://digiexplorer.info/api/addr/DNf2iFGDwfUPnSbcY8KRZBjHdTgzgrrAYm/utxo

Compared to FLO https://livenet.flocha.in/api/addr/F77pykX5Dq2ju9sxdJC4a4cYZk7xNNegH5/utxo

Seems it will be necessary to add a check for that and calculate satoshis from value if satoshis doesn't exist or to update the Explorer to a more recent API version

EDIT: Or switch the api url in digibyte.js to this other explorer that seems to be running a newer version and does return satoshis
https://digibyteblockexplorer.com/api/addr/DEoWetricML2TJE37wEPxQqjZzYWXvvkKW/utxo

werewolfe · 2019-03-21T18:44:07Z

I switched to a different explorer that returns satoshis. There is still an issue. The value is now present, but the inputs and outputs are still undefined.

When I log utxos:

werewolfe · 2019-03-22T20:24:22Z

In TransactionBuilder.js I logged coin and account as below. Variable account is returned as undefined. I think this is the issue. coin provides all of the detail about the coin and the explorer.

function TransactionBuilder(coin, options, account) {
		_classCallCheck(this, TransactionBuilder);
		console.log(coin); //Line 110
		console.log(account); //Line 111
		this.coin = coin;
		this.account = account;

		// Addresses we are sending from
		this.from = [];
		// Addresses we want to send to & amounts
		this.to = [];

		this.passedOptions = {};

		this.parseOptions(options);
	}

orpheus · 2019-03-22T22:53:04Z

line 425 can you log this again?
var selected = coinselect(utxosNoUnconfirmed, targets, Math.ceil(this.coin.feePerByte), extraBytesLength)
and every var in it? selected, utxosNounconfirmed, targets, Math.ceil(this.coin.feePerByte), and extraBytes.length; just want an updated version with the new api in one place

And then, can you show me how you're initializing the HDMW?

sendPayment(){
    let address = new HDMW.Address(this.digibyte.seed, HDMW.Networks.digibyte, false);
    this.myWallet.sendPayment({
      from: address,
      to: { "DU22gCjXbV8R43PPJXb8ichDfEVQdHJsaa": 1 },
      coin: "digibyte",
    }).then(function(txid){
      this.txid = txid;
      console.log("Successfully sent Transaction! " + this.txid);
    }).catch(function(error){
      console.error("Unable to send Transaction!", error)
    })
 }

I see here, you're creating a new instance of HDMW for new HDMW.Address but how did you init this.myWallet?

Also log this.accounts in lib/Coin.js in the constructor under (make sure discover: true)

if (this.discover){
	this.discoverAccounts()
        // log here
}

werewolfe · 2019-03-22T23:39:47Z

Would you be willing to send me the Digibytes network information and send me the smallest amount of Digitbyte to an address so I can test locally?

Sent some DGB to that address. Hopefully that's what you intended, if not then they're probably burned🙃

orpheus · 2019-03-24T18:59:43Z

haha yeah that's what I intended. It'll take me a while to get through this and get back to you. But for now, can you add the discover option to your wallet initilizatoin and tell me if you receive any errors?

constructor(){
    this.myWallet = new this.Wallet('My Mnemonic', {discover: true}); // make changes here

werewolfe · 2019-03-24T21:13:22Z

Added {discover: true}, still get the same error:

home.page.ts:55 Unable to send Transaction! Error: Unable to build Transaction 
Error: No Inputs or Outputs selected! Fail!
    at TransactionBuilder.sendTX (TransactionBuilder.js:651)

Also, when I add this the transaction takes about 35 seconds to process and show error. Seems like a long time. Is there a way to operate this as a single coin wallet?
