Solutions

1. Check that the path exists and is spelled correctly; the operation requires an existing target path.

When it happens

Trigger: A snapshot diff or related operation references a path that has been deleted or never existed.

Common situations: Running snapshotDiff or restore operations against a removed or mistyped directory.
