Workday Spoke Attach Employee Documents

[Arthur Bernardo]

Hi all,
I’m working on a Workday integration where we use the OOB Action “Get Employee Documents by Employee ID” (from the Workday spoke) to retrieve employee documents as Base64-encoded strings via SOAP API.
The Action works fine — we receive the documents, and in our custom Flow Designer Subflow, we loop over the response and try to convert the Base64 content into an attachment on a custom table.
We’ve tried multiple approaches inside a Script Step in a custom Action, including:

• GlideSysAttachment.write() using decoded strings
• Byte arrays (using charCodeAt)
• writeBase64() with all required inputs
• Using a Script Include or doing it directly in the Script Step

All return “Success”, and no errors are thrown, but the attachment is never created.
 What we’ve ruled out:

• Table allows attachments (Allow attachments is enabled)
• Scope has create access and scriptable access to sys_attachment
• We've tested the exact same code in a Background Script — and it works perfectly

Has anyone experienced this silent failure when creating attachments via custom Actions? Any advice on how to make writeBase64() or any alternative approach work within a Flow Designer Action?
Thanks in advance!
