P6 design import process fails attachment creation due to filename

[postmastersteve]

Attachment importing fails with a 500 Internal Server error and this response:

{"errors":[{"title":"Attachment creation failed."}]}

The UI correctly lets the user know the import has failed, but the import failure might be recoverable.
