Outlook doesn't recognize calendar invitation

I am trying to send an email with an calendar invitation from my system. I am using Nodemailer with AWS SES to send the email. However, when I receive the email, it is not recognized in Outlook or Apple Mail as it normally should. Instead the file is shown as an attachment like below. It works perfectly for Gmail.

enter image description here

My full mime email.

I've faced a similar problem and solve it by rewriting a Content-Type header from

text/calendar; charset="utf-8";

to

text/calendar; charset="utf-8"; method=REQUEST

When I've added method=REQUEST to header, outlook started recognise my ics file as an event.

The outer message content type is multipart/mixed. Outlook expects a single MIME text/calendar part that contains the calendar data.
