This article is to help the user overcome the 'uncommitted work pending' error when they use a clone of the SharePoint: Create Folder flow.

Why am I receiving an error below when the SharePoint: Create Folder flow is triggered?
An Apex error occurred:shpoint.customException: You have uncommitted work pending,  Please commit or rollback before calling out Error ID: 2034664232-290086 (-297330358)work pending.  

This document mentions that DML operations and SharePoint REST API transactions cannot happen in a single operation.  Follow this link to a Salesforce knowledge article that addresses the error precisely.  To bypass the error in our action methods, use the Asynchronous Method input operation = true.
