[Binance] ExchangeError while checking account status

• OS: macOS 10.14.3
• Programming Language version: Node.js
• CCXT version: 1.18.333
• Exchange: Binance
• Method: wapiGetAccountStatus

To check account status I use accountStatus endpoint. And when I specify incorrect apiKey/secret I get Exchange error with message {"msg":"API key does not exist","success":false}

I think AuthenticationError error will be more prefer in that case.

A little example:

const account = new ccxt.binance({apiKey: APIKEY, secret: SECRET});
try {
  const accountStatus = await account.wapiGetAccountStatus();
  // accountStatus.success === true - account available
  // accountStatus.success === false - account banned
} 
catch (error) {
  if (error instanceof ccxt.AuthenticationError) {
    console.error('Authentication failed')
  }
}

I know it’s specific case, but it will help in my app to make error handling more unified

PS. I found cool issue #4071

@kroitor All work correct, thanks!

@alexeymarunin i’ve uploaded a fix to this 30 minutes ago, so it should be recognized as AuthenticationError as of version 1.18.377. Let me know if that doesn’t work for you.
