error remove %d files: %w

Error message

error remove %d files: %w

What it means

Returned inside SwiftPath.RemoveAll's retry loop when the Swift bulk-delete call fails for a batch (up to 10000 objects) with something other than 404. The container refused the bulk delete — permissions, too-many-requests, or proxy error — and the error reports how many objects were in the failed batch; RetryWithBackoff re-attempts the same batch.

Solutions

1. Check container delete permissions and auth token validity
2. Rely on swiftWriteBackoff retries for transient throttling; if persistent, inspect the wrapped Swift error
3. If batches consistently fail, reduce concurrency against the Swift proxy
