Current Behavior
When performing any CLI command that references a non-existing store (not defined in the .configu file) or an existing store with a non-existing store type, the CLI outputs an uninformative error regarding the file/directory not being found.
Expected Behavior
The CLI should explicitly tell the user if the store or store type doesn't exist so that the user knows what they should fix.
To Reproduce
Use the CLI to reference a non-existing store or a non-existing store type.
