Sending attachment issue

Hello,

I started getting this error out of blue today while sending an attachment via the messages endpoint:

{"_error":{"status":400,"title":"Bad request","message":"Body did not satisfy requirements","details":["body.body: missing"]}}

The code that I am using to send the message and attachment hasn’t been changed in months and was working since this morning. 

Any idea why this would start happening all of the sudden?

This is the request that i am sending:
