Uncaught promise rejection causing program to crash

[richardkazuomiller]

Bug Report

Since https://github.com/spotify-api/spotify-api.js/blob/967f9490ea4c8b482f71f2de481bd5033ab2fd70/src/Client.ts#L130 is not awaited or called with .catch(...) after it, Node will exit if the promise returned by this._init() rejects.

It's a bit tricky because it is called in the constructor which means we can't just add await in front of it and I don't know enough about the codebase to suggest how to refactor it at the moment.

What i expected:

A failed API request should not make the process exit.

What actually happened:

A bad response when trying to refresh the token causes the process to exit

To reproduce this bug:

Difficult to reproduce because it is caused by 503 from Spotify.

You don't have to worry about the promise rejection in _init function there as the _init function involves a try catch statement. If there are any errors thrown, it is the SpotifyAPIError or the AxiosError. The package uses endpoints, resources for few endpoints are outdated as the spotify api has changed its few structures.

As i am the only one maintaining the module, it will take some time to fix this (probably more than a month). It would be better if you send the code which led to the error.
