NestJS does not propagate Passport's errors about passport

I found the problem in code:

passport/lib/auth.guard.ts

Lines 65 to 70 in 4ac8048

	handleRequest(err, user, info, context): TUser {
	if (err || !user) {
	throw err || new UnauthorizedException();
	}
	return user;
	}

This maybe changed to :

handleRequest(err, user, info, context): TUser {
      if (!user) {
        throw err || info || new UnauthorizedException();
      }
      return user;
    }

because Passport called as callback(null, false, failures[0].challenge, failures[0].status)
here is:
https://github.com/jaredhanson/passport/blob/42ff63c60ae55f466d21332306e9112295c0535e/lib/middleware/authenticate.js#L104

We have accidentally removed the section in the docs on this feature. I've just added it back https://docs.nestjs.com/techniques/authentication#extending-guards
