  WGDS_PROCESS781 - Unable to load the zip file of training data
  
  Cause:
  This error typically occurs in the context of SAP's Machine Learning Foundation (MLF) or SAP Conversational AI integration, where the system attempts to load or import training data packaged as a ZIP file but fails. The main causes include:
  
  Corrupted or invalid ZIP file: The training data ZIP file might be corrupted, incomplete, or not properly formatted.
  Incorrect file structure inside the ZIP: The expected folder or file structure inside the ZIP does not match the required format.
  File size or system limitations: The ZIP file might be too large or exceed system limits.
  Authorization or access issues: The user or system process does not have sufficient permissions to read or upload the file.
  Transport or network issues: If the file is being loaded from a remote location, network interruptions or transport errors can cause failure.
  Incorrect file path or missing file: The system cannot find the ZIP file at the specified location.

  Ensure the file is not corrupted or partially downloaded.
  
  
  
  Check the file structure inside the ZIP:
  
  Confirm that the ZIP file contains the expected files and folder hierarchy as required by the SAP training data import process.

  Validate file size and system limits:
  
  Ensure the ZIP file size does not exceed any SAP system or application limits.
  If the file is too large, consider splitting the training data into smaller chunks.
  
  
  
  Check authorizations:
  
  Verify that the user or service account performing the import has the necessary authorizations to access and upload the file.
  Check SAP roles and authorizations related to the ML or training data upload process.
  
  
  
  Confirm file path and availability:
  
  Make sure the file path specified in the import process is correct and accessible.
  If the file is on a network share or remote location, ensure connectivity and permissions.
