Document of Records payload fails if Attachment required.

Summary:

Hello

We are able to successfully create Document of Record and attachment using API (JSON).

But the issue is if the Document Type has Attachment required (Minimum Attachment > 0) in the setup, out APIs are failing. Looks like the Document of record is getting created first without attachment and it is failing.

Do you have a sample payload which works to create document of record with attachment.

Sample Payload. It works fine if Attachment is not required. We are using Base64coded for Attachment.
