Docusign composite template giving TAB_REFERS_TO_MISSING_DOCUMENT - docusignapi

Question

I was trying to use these two templates as a composite template thru the REST api. I sent out each template on its own and it worked fine. Here is the request from the log file:
Content-Length: 1526
Host: demo.docusign.net
X-DocuSign-Authentication: {"Username":"Kathleen.Jones#XXX.com","Password":"[omitted]","IntegratorKey":"[omitted]"}
X-Forwarded-For: 63.118.233.100, 104.129.194.117
{
"compositeTemplates": [
{
"serverTemplates": [
{
"sequence": "1",
"templateId": "2d743750-f910-4a30-ad34-ac5bc0ca8daa"
},
{
"sequence": "2",
"templateId": "63479d79-a776-4767-a2a3-1ebd01d7d8fa "
}
],
"inlineTemplates": [
{
"sequence": "1",
"recipients": {
"signers": [
{
"name": "Joe Blow",
"email": "JoeBlow#outlook.com",
"recipientId": "1",
"roleName": "CEO"
},
{
"name": "Kathy Blow",
"email": "KathyBlow#outlook.com",
"recipientId": "2",
"roleName": "Uber CEO"
}
]
}
},
{
"sequence": "2",
"recipients": {
"signers": [
{
"name": "Joe Blow",
"email": "JoeBloww#outlook.com",
"recipientId": "2",
"roleName": "Uber CEO"
},
{
"name": "Kathy Blow",
"email": "KathyBlow#outlook.com",
"recipientId": "1",
"roleName": "CEO"
}
]
}
}
]
}
],
"status": "sent",
"emailSubject": "Please Sign the enclosed docs at your earliest convenience"
}
400 BadRequest
Content-Type: application/json; charset=utf-8
X-DocuSign-TraceToken: cb23f0ed-6be2-4189-9237-5575671f8f4b
{
"errorCode": "TAB_REFERS_TO_MISSING_DOCUMENT",
"message": "The DocumentId specified in the tab element does not refer to a document in this envelope. Tab refers to DocumentId 15100956 which is not present."
}
Like I said, I used the 2 templates standalone and they went out fine. Any ideas?

I found the answer right here in a StackOverflow answer:
In the request JSON you posted, you're specifying "documents" (plural) as a collection/array of document objects -- which isn't correct. Each Composite Template item within the compositeTemplates array can only contain, at most, a single document.
