invalid path in swiftfs tree: %s

Error message

invalid path in swiftfs tree: %s

What it means

Internal type guard in SwiftPath.RemoveAll: the paths returned by ReadTree must all be *SwiftPath, but one entry is a different Path implementation. This indicates the tree listing was somehow mixed with another VFS backend — a programming invariant violation rather than a runtime condition — so the bulk-delete keys cannot be extracted and the purge aborts.
