Go-ethereum: Invalid hex number error for valid address

[MrHash]

System information

Geth version: 1.6.5-stable
OS & Version: OSX

Expected behaviour

Transaction is sent when receiver address is "0x088e62f69884781eb458e64b8d4e24c08a6ed9b5"

Actual behaviour

Transaction fails with:
Error: invalid argument 0: hex number has leading zero digits after 0x

Steps to reproduce the behaviour

...
var receiver = "0x088e62f69884781eb458e64b8d4e24c08a6ed9b5"
eth.sendTransaction({from:sender, to:receiver, value:amount, gas:limit, gasPrice:price});

The issue is related to "gas", "gasPrice" or "value" field. Leading zero is allowed for addresses.

[MrHash]

These were my values copied direct from the console.

> sender
"0x914ef49db7caf5e4683e671cb6caf96db73bb93b"
> receiver
"0x088e62f69884781eb458e64b8d4e24c08a6ed9b5"
> amount
"0.859867396"
> limit
"21000"
> price
"25000000000"
> eth.sendTransaction({from:sender, to:receiver, value:amount, gas:limit, gasPrice:price});

I tried sending again today to the 0x0... address with a restarted console and different values and it worked. Strange.

I'm unsure about the amount being a fractional number. I though it must be an int in Wei. Perhaps that could have been the issue?

[MrHash]

Yeh must be the amount not being an int. But in any case the error was misleading.

FYI, here is error message from master

eth.sendTransaction({from: eth.coinbase, to: "0x0166be393b7ded951d9c171d1241312a588014d2", value: "0.85"});

Closing because the error message is improved now.

[SCBuergel]

Just leaving a note here cause I ran into this on an old machine: value should be an integer (in Wei) and not a fraction of an Ether.

[TechnoFer]

invalid argument 0: json: cannot unmarshal hex number with leading zero digits into Go struct field CallArgs.value of type *hexutil.Big

what is this

[caochao]

cannot unmarshal hex number with leading zero digits into Go struct field CallArgs.gas of type hexutil.Uint64
what is this

[karalabe]

Don't pass number arguments with leading zero digits.

My solution is to replace leading zero directly at the library. Looks like that:

Eth.prototype.sendAsync = function sendAsync(opts, cb) {
  if (opts.method == "eth_estimateGas"){
    if (opts.params[0].value.toString()[2] === '0')
        opts.params[0].value = opts.params[0].value.toString().replace('0x0', '0x');
  }
  var self = this;
  self.idCounter = self.idCounter % self.options.max;
  self.currentProvider.sendAsync(createPayload(opts, self.idCounter++), function (err, response) {
    var responseObject = response || {};
    if (err || responseObject.error) return cb(new Error('[ethjs-query] ' + (responseObject.error && 'rpc' || '') + ' error with payload ' + JSON.stringify(opts, null, 0) + ' ' + JSON.stringify(err || response.error, null, 0)));
    return cb(null, response.result);
  });
};
