How do I throw an array from GraphQLError?

[matheuspleal]

To give an example, when this mutation is performed:

mutation Mutation($name: String!, $email: String!, $password: String!, $birthdate: Date!) {
  signUp(name: $name, email: $email, password: $password, birthdate: $birthdate) {
    user {
      id
      name
      email
      birthdate
      age
      createdAt
      updatedAt
    }
  }
}

If no value is assigned to the variables, an errors array is returned with the missing fields:

{
  "errors": [
    {
      "message": "Variable \"$name\" of required type \"String!\" was not provided.",
      "locations": [
        {
          "line": 1,
          "column": 19
        }
      ],
      "extensions": {
        "code": "BAD_USER_INPUT",
        "stacktrace": [
          "GraphQLError: Variable \"$name\" of required type \"String!\" was not provided.",
          "..."
        ]
      }
    },
    {
      "message": "Variable \"$email\" of required type \"String!\" was not provided.",
      "locations": [
        {
          "line": 1,
          "column": 35
        }
      ],
      "extensions": {
        "code": "BAD_USER_INPUT",
        "stacktrace": [
          "GraphQLError: Variable \"$email\" of required type \"String!\" was not provided.",
          "..."
        ]
      }
    },
    {
      "message": "Variable \"$password\" of required type \"String!\" was not provided.",
      "locations": [
        {
          "line": 1,
          "column": 52
        }
      ],
      "extensions": {
        "code": "BAD_USER_INPUT",
        "stacktrace": [
          "GraphQLError: Variable \"$password\" of required type \"String!\" was not provided.",
          "..."
        ]
      }
    },
    {
      "message": "Variable \"$birthdate\" of required type \"Date!\" was not provided.",
      "locations": [
        {
          "line": 1,
          "column": 72
        }
      ],
      "extensions": {
        "code": "BAD_USER_INPUT",
        "stacktrace": [
          "GraphQLError: Variable \"$birthdate\" of required type \"Date!\" was not provided.",
          "..."
        ]
      }
    }
  ]
}

However, if I want to throw a custom exception, the documentation shows how to use GraphQLError (here)

But in this exemplified behavior, I can only throw one exception, that is, the errors array returned by the apollo server, contains only one object

Could anyone help me please?
