Auth0 provider doesn't attribute all the values to goth.User

[justman00]

Hey,

so I noticed that Auth0 is sending some more data back, e.g:

{
        "email": "email@example.com",
        "email_verified": true,
        "family_name": "Example",
        "given_name": "Example",
        "locale": "en",
        "name": "Example Example",
        "nickname": "example.example",
        "picture": "<picture url>",
        "sub": "google id or other provider id",
        "updated_at": "2021-10-21T08:52:15.784Z"
    }

but the provider seems to be reading only these values:

type auth0UserResp struct  {
	Name      string `json:"name"`
	NickName  string `json:"nickname"`
	Email     string `json:"email"`
	UserID    string `json:"sub"`
	AvatarURL string `json:"picture"`
}

I want to know if other values, such as family_name or given_name are not parsed on purpose because they can be left empty by Auth0 or if it was just overlooked?

@justman00 To answer your question directly: it was an oversight, not intentional.

given_name and family_name are part of the OIDC standard claim set and Auth0 returns them whenever the user provided a name. The Google provider already maps them to goth.User.FirstName / goth.User.LastName (providers/google/google.go) — Auth0 should do the same. Picture, name, email, sub, and nickname were mapped; given_name and family_name just got dropped.

Opened #643 with the fix. It adds both fields to auth0UserResp and userFromReader. The unmapped claims you also listed (email_verified, locale, updated_at) don't have typed slots on goth.User, so they stay accessible via user.RawData — added an assertion to Test_FetchUser to lock that contract in.
