Help on a API Error - Composite End point

We are exporting invoice data to the composite end point.

We have 14 line items and are updating a document item tag on each line, all from within the one post.

 

I am getting the following error from the API

 

"errorCode":"LIMIT_EXCEEDED",

"message":"The request can’t contain more than 25 operations."

 

 

Can anyone suggest how we might able to use the composite end point to raise an invoice with this many lines?
