making a copy and replacing it in your workflow is NOT required. There is a command "Mount Volume' already available which can work for you and.
And this should continue to work seamlessly even when the fix is available.
So in your workflow, add this command next to the 'Clone volume' command.
In 'Parameters for Mount Volume' Select doopdown 'Using a previously defined volume'.
Now select the volume defined as 'Clone' in 'Clone Volume' command.
In tab 'Other Parameters' parameter Juntion_path is available for you.
That's all done.
See the image below to help you.
