## Why it fails

- An attached document (`cbc:EmbeddedDocumentBinaryObject`) has a `mimeCode` outside the allowed list, such as `application/octet-stream` or `application/msword`.

## How to fix it

- Attach the document as PDF, PNG, JPEG, CSV, XLSX or OpenDocument spreadsheet, with its matching MIME type.
