AEM Forms - Missing attachments in DoR for Adobe Sign

Hi,

I have an adaptative form based on a XDP template which have the File Attachment component to add needed files for the form. The attachemnts are being stored OK under the payload defined folder. But when I summit the form to generate the DoR to be sended to Adobe Sign the attachments are missing in DoR/PDF.

I have done a research in the adobe documentation but I could not find anything about it. Why the attachments of the adaptative form are not added to the DoR for Adobe Sign?

Thanks,

Fernando
