DocuSign Request error "Envelope definition missing." - salesforce

Question

I am trying to make 'createAndSendEnvelope' request using DocuSign REST api/v2. My JSON is valid.
I came across the same question and I tried the solution given in there i.e. I made sure all new lines use '\r\n'.
What am I missing here? Here is my request, I get error code, "message": "The Envelope is not Complete. A Complete Envelope Requires Documents, Recipients, Tabs, and a Subject Line. Envelope definition missing."

You can specify your base64 encoded document bytes in the documentBase64 property
POST https://demo.docusign.net/restapi/v2/accounts/xxxxx/envelopes HTTP/1.1
