Document Builder - Error when attaching to Row.

I've set up a system where we use the Document builder to create a PDF report with some text and photos for customers. It seemed to work well, however it's been throwing some weird errors.

If I choose Attach to row it will create the PDF, but error when trying to attach it to the row.

If I download it to my computer and then go back into the document and attach it manually, it works.



Anyone have any idea what this means?

Thanks
