I synced Wordpress to Airtable using Zapier. Whenever I submit a form on Wordpress, the information is shown automatically in Airtable. However, the only issue I am facing is that attachments are not showing at all. I have a form field where users can upload their profile pictures. 

The attachment in Airtable shows empty. Only if I upload directly an image from Airtable the image is shown (Row 2). However, that is not what I want. I want the image submitted in the wordpress form to show in Airtable. 

Any idea where the issue might come from? Thank you for taking the time and helping!
