To your first question, I am not creating a project within a project because in that path: /GameStop/projects/TargetProject, projects is a project space and already exist. I am trying to create TargetProject inside the already exiting projects space. I have all rights and permissions to create and delete projects in that dev org.
You are correct about my first question. I was thinking of something else.
I know other’s have seen the message you are seeing if they have forgotten to change the asset type. Otherwise, try removing the leading /. I was able to create a project for my path org/projects/projectname, but saw the same message if the path was /org/projects/projectname.
Solved the issue, by adding a mapper with snap.outputViews.
