Amazon Simple Storage Service (S3) is a scalable object storage service provided by AWS. It is designed to store and retrieve any amount of data from anywhere on the web. S3 is commonly used for backup and restore, data archiving, and as a data lake for analytics.
When working with Amazon S3, you might encounter the InvalidPart
error during a multipart upload. This error indicates that one or more of the specified parts could not be found in the multipart upload process.
During a multipart upload, you may receive an error message stating: "The part number you specified could not be found. Please ensure that the part number is correct and that the part has been uploaded."
The InvalidPart
error occurs when there is a mismatch between the parts specified in the upload request and the parts that have been successfully uploaded to S3. This can happen due to incorrect part numbers or missing parts.
To resolve the InvalidPart
error, follow these steps:
Ensure that the part numbers specified in your complete multipart upload request match the part numbers of the uploaded parts. You can list the parts using the AWS CLI:
aws s3api list-parts --bucket <bucket-name> --key <object-key> --upload-id <upload-id>
Verify that all parts have been uploaded successfully. If any parts are missing, re-upload them using the following command:
aws s3api upload-part --bucket <bucket-name> --key <object-key> --part-number <part-number> --upload-id <upload-id> --body <file-path>
Once all parts are verified and uploaded, complete the multipart upload:
aws s3api complete-multipart-upload --bucket <bucket-name> --key <object-key> --upload-id <upload-id> --multipart-upload file://<json-file>
For more information on multipart uploads, refer to the AWS S3 Multipart Upload Overview. If you encounter further issues, consult the CompleteMultipartUpload API Documentation.
