Uploading an Edgeworker with -CodeDirectory fails on MacOS when it has subdirectories

I am uploading a code directory with the following command:

$ New-EdgeWorkerVersion -section mysection -EdgeWorkerID 123456 -CodeDirectory ./dist

This has been working fine. But as soon as I create a subdirectory (in this case dist/utils). The tarball fails to upload.

$ New-EdgeWorkerVersion -section mysection -EdgeWorkerID 123456 -CodeDirectory ./dist
Invoke-AkamaiRequest: /Users/user/.local/share/powershell/Modules/Akamai.EdgeWorkers/2.3.2/Functions/Public/New-EdgeWorkerVersion.ps1:90
Line |
  90 |      $Response = Invoke-AkamaiRequest @RequestParams
     |                  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     | HTTP 400 - Invalid Argument - Tarball validation failed: Invalid file permission : The ._utils file cannot be executable. See $Error[0].exception.data for more information

As a workaround I have kept the files in the root, without subdirectories.

I am on MacOS.

In contrast, the Akamai CLI (not powershell) does succeed to upload it.

$ akamai --section mysection edgeworkers upload --codeDir ./dist 123456

Running edgeworkers command... [OK]

Start at Functions/Public/New-EdgeWorkerVersion.ps1:90 and trace how the -CodeDirectory ./dist input is turned into the uploaded tarball. Reproduce the failure on macOS with a nested dist/utils directory, then compare the resulting archive behavior with the successful Akamai CLI upload. Done means nested directories upload without invalid executable metadata files.
