Copy several attachments from one Airtable record to another

Hi

I thought this would be really easy to do, but I just can’t manage it!

I want to copy all the attachments from one Airtable record to the same field on another record.

I’ve passed the current RecordID into Make (Which is the record that needs to receive the attachments), and also the “Previous” recordID (which is the ID of the record which has the attachments to copy over.

I assumed I could just retrieve an Airtable record (using the previous record ID) and pass the array straight into an update record module. But I got a runtime error (See screenshot)

Should I be using an iterator (or an agregator)? I’ve tried both but can’t get it to work! I can get the first attachment to copy over, but not all of them.

Any help much appreciated!
