Issue Description

Hello,

I am using graphql-constraint-directive with apollo-server-express But in formatError, when I call error.originalError it always return undefined. Here my code:

const { constraintDirective, constraintDirectiveTypeDefs } = require('graphql-constraint-directive')
const express = require('express')
const { ApolloServer } = require('apollo-server-express')
const { makeExecutableSchema } = require('graphql-tools')
const typeDefs = `
  type Query {
    books: [Book]
  }
  type Book {
    title: String
  }
  type Mutation {
    createBook(input: BookInput): Book
  }
  input BookInput {
    title: String! @constraint(minLength: 5, format: "email")
  }`
const schema = makeExecutableSchema({
  typeDefs: [constraintDirectiveTypeDefs, typeDefs],
  schemaTransforms: [constraintDirective()]
})

const formatError = function (error) {
  if (error.originalError && error.originalError.code === 'ERR_GRAPHQL_CONSTRAINT_VALIDATION') {
    // return a custom object
  }

  console.log(error);

  return error
}

const app = express()
const server = new ApolloServer({ schema, formatError })

server.applyMiddleware({ app })

app.listen({ port: 3000 }, () =>
  console.log(`🚀 Server ready at http://localhost:3000${server.graphqlPath}`)
);

Please help me how can I fix it.

I fixed returning my errors to the frontend by adding the following code:

    formatError: error => {
      // @ts-ignore
      if (error.originalError?.originalError?.code === 'ERR_GRAPHQL_CONSTRAINT_VALIDATION') {
        // @ts-ignore
        return {
          // @ts-ignore
          ...error.originalError?.originalError,
          message: error.originalError?.message,
          name: 'UserInputError',
          code: 'BAD_USER_INPUT',
        };
      }
      return error;
    },

How are you using it? The debugger or console.log(util.inspect(error, {showHidden: true, depth: null})) should show the details. From what I recall, either GraphQL or Apollo defines them as hidden properties so a simple console.log won’t show them.
