Support onError hook during the init phase

[sobolevn]

What problem does this feature solve?

Currently the suggested way to bind your own error hooks is by defining a custom plugin:

// plugins/auth.js
export default function({ $auth }) {
  $auth.onError((error, name, endpoint) => {
    console.error(name, error)
  })
}

And then extending the auth config like so:

{
  modules: {
    '@nuxtjs/auth'
  },
  auth: {
     plugins: [ '~/plugins/auth.js' ]
  }
}

But, the problem is that when some error happens during $auth.init().
In this case _errorListeners is not yet populated, so there's no way to intercept this error.

In my case this is token expiration error from one of the oauth providers.

How about providing any mechanism to handle errors during init()?

I have this exact same issue. I want to handle an error during init() gracefully, but there's no proper way to load error listeners before the Init.

I though it would be best to just go ahead and create a PR myself.

This should be fixed in v4.6.0 by #234. Please ping here if the issue still exists.
