Bug fixes

• MultipartUpload & MultipartUpload_S3: Fixed a race condition where triggerSingleFileUploadComplete was called before the multipart upload had finished processing.
  • Occurrence: When using multipart upload (files larger than 20MB), triggerSingleFileUploadComplete would fire prematurely before the upload was fully complete.
  • Root cause: triggerSingleFileUploadComplete was invoked outside the completeMultipartUpload callback, causing it to execute before the async operation resolved.
  • Solution: Moved triggerSingleFileUploadComplete inside the .then() handler of completeMultipartUpload, ensuring it only fires once the upload is fully complete.

Improvements:

• Performed minor architectural refactoring by moving the polling action "CheckHasProcessFinished" from "MultipartUpload_CS" to "MultipartUpload_CW" to improve code maintainability and separation of concerns.

Improvements:

• Refactored the "MultipartUpload_CW/Client Actions/MultipartUpload/CompleteMultipartUpload" Action to implement BPT & short-polling for file part concatenation, replacing the previous single-Server Action approach where you had to increase the "Server Request Timeout" property based on the upload file size.
• Decoupled AWS S3-related components from the "MultipartUpload_CS" module to a separate "MultipartUpload_AmazonS3_CS" module, improving modularity and enabling independent updates to S3-specific functionality.
