Scalar root field (string) only returns undefined

[nikolasburk]

What is the expected return value of a generated function on query when the root field is a scalar?

Consider this example:

const { makeExecutableSchema } = require('graphql-tools')
const { Binding } = require('graphql-binding')

const typeDefs = `
  type Query {
    hello(name: String): String
  }
`

const resolvers = {
  Query: {
    hello: (parent, { name }) => `Hello ${name || 'World'}`,
  },
}

const schema = makeExecutableSchema({ typeDefs, resolvers })

const helloWorldBinding = new Binding({
  schema,
})

helloWorldBinding.query.hello().then(result => console.log(result))

With the current implementation, it prints only undefined.

I'd expect this to print either Hello World or { hello : 'Hello World' }.

This definitely looks like a bug. We should also make sure to add some more test coverage for this.

I'm trying to debug this one. We have a separate issue for test coverage (#13)

It seems to have something to do with the way we create the info object.
Update: found the cause. This will be fixed in the next release.

We actually had a test for this, but the assertion was incorrect.
