📄 Steps to Reproduce

  2. Attempt either of the following download operations:
    • A. Single URL Download: Input a specific media URL and initiate the download.
    • B. Custom Download: Select a group of media files for a custom task and start the download.
  3. The error occurs frequently and intermittently during the download process, leading to job interruption.
