gatsby-transformer-json Not parsing single objects

Description

I'm using Netlify CMS to save a list of data (testimonials example) https://www.netlifycms.org/docs/widgets/#list . The output of this when saved is in the format of

{
  "testimonials": [
    {
      "testament": {
        "name": "Jessica Parke",
        "company": "WallSteet",
        "quote": "These people are amazing"
      }
    }
  ]
}

Steps to reproduce

Simply add the below format to any JSON file:

{
  "testimonials": [
    {
      "testament": {
        "name": "Jessica Parke",
        "company": "WallSteet",
        "quote": "These people are amazing"
      }
    }
  ]
}

lets call this file testing.json. In any page, inside the graphql query run the following (as per the docs)

allTestimonialsJson {
      edges {
        node {
          testimonials {
            testament {
              name
              company
              quote
            }
          }
        }
      }
    }

Expected result

It should compile fine and work

Actual result

We end up with an error that just crashes on compiling

GraphQL Error Unknown fieldallTestimonialsJsonon typeRootQueryType``

Note that the plugin works fine when i'm working with a similar format, but only when its in an array state, i.e:

[
  {
      "testament": {
        "name": "Jessica Parke",
        "company": "WallSteet",
        "quote": "These people are amazing"
      }
    }
]

The issue however persists even when we have a single object in the JSON file, the plugin, from my brief experience with it, isn't a fan of the parent data structure being an object as to an array.

i.e

{ "bob": "marley"}

doesn't work, however

[{"bob": "marley"}] works.
