Upgrade AWS CLI to Fix Zero-byte File Upload Error

Medium Risk

The error occurs due to a known issue in the AWS CLI version 1.11.13 where the handling of zero-byte files is not properly managed, leading to an incorrect number of arguments being passed to the 'seek()' function. This bug has been addressed in later versions of the AWS CLI.

    Check Current AWS CLI Version

    Uninstall Current AWS CLI Version

    Remove the existing version of AWS CLI installed via the package manager to avoid conflicts with the new installation.

  5. 5

    Test Upload of Zero-byte File

    Attempt to upload the previously failing zero-byte file to verify that the issue has been resolved with the new version.

    bash
    aws s3 cp path/to/zero-byte-file s3://your-bucket-name/

Validation

If the upload of the zero-byte file completes successfully without any errors, the fix has worked. Additionally, ensure that other files can still be uploaded without issues.
