HELP Backend Workflow

Hello,

I need your help because my workflow is not working and I’m stuck…
I want to download all my .pdf invoices and put them in the .pdf field. To retrieve them I go through an API request with a block_hash as they are on the blockchain. I’d like to copy them into the database. To do this, I’ve created a backend workflow as soon as the page is loaded, as shown below. But this copies the same invoice everywhere… I want to modify all the invoices in my repeating group.

Thanks for your help.
