You tried to create a JSON string using text operations. Then the reference to the document turns into "[Document:xx]". Now, you try to turn this into a dictionary. How should Appian know what you are referring to?

Amazing that worked with one small change, line 18 should be "contentBytes": toDocument(fv!item)

Thank you v much!

Use the following code in your "attachments" attribute

"attachments": {
      if(
        a!isNullOrEmpty(ri!attached),
        {},
        a!forEach(
          items: ri!attached,
          expression: {
            "@odata.type": "#microsoft.graph.fileAttachment",
            "name": concat(
              document(fv!item, "name"),
              ".",
              document(fv!item, "extension")
            ),
            "contentType": concat(
              "application/",
              document(fv!item, "extension")
            ),
            "contentBytes": fv!item
          }
        )
      )
    }
