Attempting to provide a document to override a server template causes Unspecified error An item with the same key has already been added

Question

I'm attempting to port code that uses the Docusign SOAP API method CreateEnvelopeFromTemplatesAndForms to the REST API. I used this page of the Rest API Reference - Send an Envelope from a Template

I've hit a roadblock in that when I try to specify a document to post to override the server template's document, I get an Unspecified error, 'An item with the same key has already been added'.

The code I'm porting over uses two inline templates and a server template.

The server template can contain one or more documents that I want to override with local documents. In the SOAP method, the documents are specified in the first inline template. The server template is specified next. And the second inline template is third in the sequence and has the recipients and custom fields. These are all added to the envelope property of the inline template.

Inline Template - Docs
Server Template
Inline Template - Recipients and Custom Fields

In the REST api, there doesn't seem to be an envelope property for the inline template and no clear migration guide between SOAP and REST that I could find. If I exclude my 'documents' property from the inline template, the envelope sends. I get the same error if I try using the document property of compositeTemplate. Here is my web request:

Thanks in advance.

I've also already looked at Incorrectly applied server templates with multiple composite templates and Adding documents to envelopes using composite templates in DocuSign with little luck.

Update

After trying the answer by WTP API below, I experimented some more. I found that the envelope would send with the correct document if I either include the base64 of the document or if I simplified the headers sent with the document bytes to just be Content-Disposition:documentId=1 instead of all the headers shown here: Docusign Rest API - Send an Envelope From a Template
