Pipeline Failed with Error code 2451
Hello henryeleonu
This typically occurs when the Notebook attempts to modify a file in the destination storage account that has been changed since the pipeline started, triggering an ETag mismatch.
Concurrent File Changes
• Check for external processes modifying files mid-pipeline.Verify `Storage Blob Data Contributor` role for destination storage.
Explicitly set file formats (e.g., `binary`).
• Use unique filenames/temp folders to avoid overwrites.See if this helps
