[gatsby-transformer-json] Filter data by attribute

[signalwerk]

When using gatsby-transformer-json filtering an array doesn't work:

data.json

{
  "foo": [
    {
      "name": "Name 1"
    },
    {
      "name": "Name 2"
    }
  ]
}

graphQL

{
  dataJson(foo: {in: {name: {ne: "no match"}}}) {
    foo {
      name
    }
  }
}

error

{
  "errors": [
    {
      "message": "Cannot read property 'id' of undefined",
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ],
      "path": [
        "dataJson"
      ]
    }
  ],
  "data": {
    "dataJson": null
  }
}

It's the same if the data-array has an id-attribute in the object.

gatsby v1.9.45

@MarBleck nope. I didn't look into it anymore. Keep me posted if you find a solution.
