Symptoms

Cannot use certain methods on a SharePoint smartobject, cannot seem to duplicate on another smartobject. I have already created a complicated view on this smart object so I don’t just want to remove and recreate and I don’t know if it would work anyway.
We have applied to cold fixes the SharePoint service broker since upgrading to 4.6.11 but this does not seem to be specific to all or any other SharePoint smart objects like the other problems
When using the methods “Get List Item by ID” or Get list item by Title” or get list Item by Name” get the 404 error below
“The remote server returned an error: (404) Not Found.”
I have tried reregistering the site and refreshing the smart object none of which work
