sendgrid-go inbound.Parse fails with panic.

[phat-innomizetech]

I've set up Inbound Email Parse Webhook. In the webhook I use https://github.com/sendgrid/sendgrid-go lib.

inbound.Parse method fails with a panic for some of the received HTTP requests
I used example raw data with parseRawEmail function from Inbound parse helper and get errors : panic address or nil pointer dereference

Raw example:
--001a11447dc881e40b0537fe6d58
Content-Type: text/plain; charset=UTF-8

This is a test email with 1 attachment.

--001a11447dc881e40b0537fe6d58
Content-Type: text/html; charset=UTF-8
Content-Transfer-Encoding: quoted-printable

This is a test email with 1 attachment.
