      "message": "The product's required option(s) weren't entered.
Make sure the options are entered and try again.",
      "category": "graphql-input",
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ],
      "path": [
        "addSimpleProductsToCart"
      ]
    }
  ],
  "data": {
    "addSimpleProductsToCart": null
  }
}

Actual result (*)

1. GraphQL:

{
  "errors": [
    {
      "message": "The product's required option(s) weren't entered.
Make sure the options are entered and try again.\n
The product's required option(s) weren't entered.
Make sure the options are entered and try again.",
      "category": "graphql-input",
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ],
      "path": [
        "addSimpleProductsToCart"
      ]
    }
  ],
  "data": {
    "addSimpleProductsToCart": null
  }
}

If it is the feature then it's worth to document the benefits of such behaviour with usage example. Guidelines or devdocs are good places for this.

Please use #421 as a reference. Need to rework the PR and use Magento\Framework\Exception\AggregateExceptionInterface for this implementation.
