hi prisma people , could you help me with this code? THANKS

The lack of formatting is making my eyes bleed a bit; however, your problem is that you aren’t returning a value from your resolver. You just have a value statement (that is likely optimized away). Use this instead.

const schema = {
  schema: {
    typeDefs: /* GraphQL */ `
      type User {
        lname: String
        fname: String
     }
     type Mutation{
      addUser(lname: String, fname: String): User!
    }
    `,
    resolvers: {
      Mutation: {
        addUser: () => {
          return {
            fname: "salut",
            lname: "coucou",
          }
        }
      }
    },
  }
}

cool😅

That looks munged. Check your parentheses. Also, if you put your code samples between two sets of three backticks → ``` ←, it’ll be formatted to be easier to read.

Adding the original code posted in this thread, to keep the conversations stremalined:

const schema = {schema: {
    typeDefs: /* GraphQL */ `
      type User {
        lname: String
        fname: String
     }
     type Mutation{
      addUser(lname: String, fname: String): User!
    }
    `,
    resolvers: {
           Mutation: {
         addUser: (__: any,_: any) => {
           {
            lname: "coucou"
            fname: "salut"
           }
         }
       }
    },
 }}
when i doing this
mutation{
  addUser{
    lname
    fname
  }
}
