Symptoms
SharePoint smart object gives 404 error on "Get list item by ID ..." methods does work on "Get List Items" and other methods. This appears to be the only SharePoint smartobject that does this. The SharePoint list and smart objects has been deleted and recreated and still gives a 404 error when using any get list item method.
This list was copied from another environment and has a lot of columns (we do have larger lists). A small test list created does not have this problem

This was identified to happen with the Get List Items By ID method from the lists. The Get List Items works fine.
Resolution
This was identified as a bug in 4.6.11 and resolved in 4.7. A TFS item has been created to address the issue.
