Snak Call Error

[deenario]

I am testing burrow and snak with your given example of a calculator. The error i am getting is that when i give it a function name that is in the contract it gives me an toUpperCase error.
Type error.

danyal@danyal-HP-EliteBook-8470p:~/burrow $ snak call Calculator Mul 5,5

I fixed the error myslef. Inside your snak Node_modlues in

DevPipe.prototype.call = function (txPayload, callback) { var address = txPayload.to var from = txPayload.from if (!from) { from = this._accountData.default } var data = txPayload.data if (data.length > 1 && data.slice(0, 2) === '0x') { data = data.slice(2) } this._burrow.txs().call(from, address, data, function (error, data) { if (error) { callback(error) } else { callback(null, data.return.toUpperCase()) } }) }

In the callback you were the data.returns with a small 'r' while the data was return like .

{ Return: '000000000000000000000000000000000000000000000000000000000000000A', GasUsed: 152 }

I modifled your callback line

From

else {
      callback(null, data.return.toUpperCase())
    }

to

else {
      callback(null, data.Return.toUpperCase())
    }
