UnhandledPromiseRejectionWarning when making request with expired token and no callback/refresh supplied

[Liam-OShea]

Hey,

I noticed that as of version 4.0.0 I no longer receive an error message alerting that the access token has expired when a request is made with an expired access token (not using the newly implemented token refresh functionality).

Instead I receive two UnhandledPromiseRejectionWarnings:
My Code:

var YahooFantasy = require('yahoo-fantasy');
var yf = new YahooFantasy(
  clientKey,
  clientSecret,
);
yf.setUserToken(
  accessToken
);

// Game
games = async () => {
  try{
    const data = await yf.user.games()
    console.log(data)
  } catch (err){
    console.log(err)
  }
}
games();

The error

To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)

I have run the following code to get more info:

process.on('unhandledRejection', (reason, p) => {
  console.log('Unhandled Rejection at: Promise', p, 'reason:', reason);
  // application specific logging, throwing an error, or other logic here
});

And receive this:

Hey @LudicrousLiam, catching up on all the issues while I'm here...

Can you verify this is still happening with 4.1.2? I'm happy to fix this but the hour wait while my token expires is a bit of a pain... I'll try to take a look tonight, but if you could confirm that would be great.
