UnhandledPromiseRejectionWarning: Unhandled promise rejection

[helxsz]

blinktrade.connect().then(function() {
	return blinktrade.login({ username: config.key, password: config.password });
}).then(function(logged) {
	console.log("Connected BlinkTradeWS")
})

My node is v8.9.4 and npm 5.6.0, and I am using the latest version of BlinkTrade, when I was running the code, i got the error as shown below.

(node:9502) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): undefined

Same here, but it happened once, now when I try to connect again I got this:

/Users/inc/Desktop/Foxbit/node_modules/blinktrade/lib/wsTransport.js:163
throw new Error('Error: ' + data.Detail + ' ' + data.Description);
^

@helxsz We were under maintenance this week, it was expected since our servers were off.

@hadnet Does it still happen? i can't reproduce it with this code

const { BlinkTradeWS } = require('blinktrade')

const blinktrade = new BlinkTradeWS({
  brokerId: 4,
  prod: true,
})

blinktrade.connect().then(() => {
  console.log('connected')
})

@cesardeazevedo it does. But it happens when I try to send a buy/sell order.

[cesardeazevedo]

@hadnet i gotcha, i've fixed and release at 0.0.20.

Let me know if you guys have any other issue.

[hadnet]

@cesardeazevedo same as the error above, just this line changed: BlinkTradeWS.onMessage (/Users/inc/Desktop/Foxbit/node_modules/blinktrade/lib/wsTransport.js:164:15) [in error above was 163:15]. It seems something with cancel or update.

[cesardeazevedo]

@hadnet I can't help you without a minimum information and way that i could reproduce it, what exactly you are trying to do? which part the exception occur? which function are you calling? can you post a small code that i could take a look?

[hadnet]

@cesardeazevedo Now it's suddenly working ok. Thanks anyway.
