CB is not a function

[Emanuelboi]

Hi all,

I'm running into an error when I tried to run the script.

` cb(null, _.keyBy(response.accounts, 'number'));
^

TypeError: cb is not a function`

I'm a newbie with Node.JS, is there something I didn't do well?

Thanks! :)

I guess the first thing to ask is, are you passing a function as a callback after your call to the API returns?

To be quite frank, I'm not a Javascript developper, but I'm willing to learn!

I was under the impression that this code was working out of the box, once Node.js was installed. Should I need to adjust some of the code to make it work, if so, do you know where I should start or which documentation I should read to be able to make it work?

Thanks!

It really depends what you are trying to achieve/do. This package wraps the Questtrade oAuth/REST API with functionality for Node. There's nothing stopping you from using the API directly, also. That's what I ended up doing. If you are not familiar with callbacks and/or JS promises, I would start there.

I'm reasonably good at Javascript, and I tried this and ran into problems:

var Questrade = require('questrade');
var qt = new Questrade('./api-key.txt');
qt.on('ready', function () {
	// Get Market quotes
	qt.getQuote('MSFT');
})

The first issue I discovered was that it did a qt.getAccounts() without me explicitly calling it. So, I changed my Questrade user app to allow "Retrieve balances, positions, orders and executions". That solved the first issue.

The second issue, when calling qt.getQuote('MSFT'), is that Questrade responds back with "Requesting anything other than 'application/json'", and since no quote data is returned, it throws that cb error again!

So, I'm still figuring this out, and I'll let you know what I find.

ok, I managed to get it to work.

1. A callback function cb is required for almost all the API calls.
   So, don't call qt.getQuote(...),
   instead call qt.getQuote(..., function(err,response) { .... } );.

2. qt.getQuote('MSFT') will not work. You have to use qt.getSymbol('MSFT',...) first to get the internal numeric id, and then use that to getQuote.

So, try this code:

var Questrade = require('questrade');
var qt = new Questrade('./.my-questrade-api-key');   //Location of a text file with the API key

qt.on('ready', function () {
	qt.getSymbol('MSFT', function(err,response) {
		console.log("getSymbol(MSFT) response:", JSON.stringify(response));
		let symbolId = response.symbolId;
		qt.getQuote( symbolId, function(err,response) {
			console.log(`getQuote(${symbolId}) response:`, JSON.stringify(response));
		});
	});
});

Thanks! I try it out, it didn't fully work for me, but I managed to make it work to retrieved my balances (that was my main goal).

This is the code that works for me:

`var Questrade = require('questrade');
var qt = new Questrade('./.my-questrade-api-key'); //Location of a text file with the API key

qt.on('ready', function () {
qt.getBalances(function (err, balances) {
console.log("getBalances() response:", JSON.stringify(balances));
});

});`
