parser constructor error

[jasan-s]

Issue Summary

I am getting the following error when using inbound-parse feature from sendgrid:

uncaught, handler, error TypeError: Reduce of empty array with no initial value
    at Array.reduce (<anonymous>)
    at Parse.keyValues (/Users/jasan/Documents/coding/sendgrid-parse-api-example/node_modules/@sendgrid/inbound-mail-parser/src/parser.js:54:8)

I believe it is due to the constructor in this parser.js:

 constructor(config, request) {
    this.keys = config.keys;
    this.request = request;
    this.payload = request.body || {};
    this.files = request.files || [];
  }

after changing the line:
this.payload = request.body || {} to ==> this.payload = request.payload || {}

it seems to work fine.

Technical details:

using the "@sendgrid/inbound-mail-parser": "^6.2.1"

Hi @jasan-s,

Thanks for the heads up @jasan-s! I've added this to our backlog for a fix.

With Best Regards,
