Adobe Sign to Sharepoint or OneDrive via Power Automate - File Cannot Be Previewed or Opened

I've used the basic Power Automate flow to save a copy of a signed document to either a Sharepoint location or a OneDrive location.  Connecting and setting up was easy.  Once the document is approved, it creates a file in the location.  However, the file cannot be previewed or opened at all.

When I try to open the file from Sharpoint or OneDrive inAdobe Pro, I get this message:

"Adobe Acrobat could not open FILENAME because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded).

To create an Adobe PDF document, go to the source application. Then choose Save as Adobe PDF from the PDF dropdown in the Print dialog."

I've tried this with numerous documents, and the result is always the same.  Any ideas on how to make this work?
