Mutation token all way return a null Graphql

Question

I try to create a token using JWT and a GraphQL server

I just have this resolver.

But when I try to do the consults:

mutation authenticatedUser($input:authenticatedUserInput){
    authenticatedUser(input:$input){
      token
    }
    
  }

I just get this:

{
  "data": {
    "authenticatedUser": {
      "token": null
    }
  }
}

This is how I am using the server:

const server = new ApolloServer({
    typeDefs,
    resolvers,
})

What I am doing wrong here? I am new to GraphQL. Thanks for any help in advance.

Answer 1

In this case, I go deep in apollo documentation and I have to return something like this.

authenticatedUser: (_, { input }) => {
      const {email} = input;
      const token = jwt.sign({ email }, process.env.SECRET_KEY, { expiresIn:'24h' });
      return {token}
    }
  },

no like

return token
