Current behavior

https://docs.nestjs.com/techniques/authentication#graphql has a fine example on passport-local with nestjs. Thank you!

But unfortunately I could not find an example on how to implement the login mutation. I mean I suppose return this.authService.login(req.user) but since my login resolver method is

auth.resolver.ts

    @Mutation()
    @UseGuards(LocalAuthGuard)
    async login(@Args('data') data: LoginInput): Promise<string> {
        return this.authService.login(?????); 
    }

auth.gql

input LoginInput {
  email: String!
  password: String!
}

type Mutation {
   login(data: LoginInput!): String!  # I suppose it returns a jwt!
}

So how can I provide the user object is such context?

P.S.: Considering the same service, module, etc. from that example

Expected behavior

To have an example of login resolver in the GraphQL section in that page, or a complete sample of GraphQL authentication with passport in https://github.com/nestjs/nest/tree/master/sample

Minimal reproduction of the problem with instructions

N/A

What is the motivation / use case for changing the behavior?

I cannot complete the tutorial.
