API Workflow on List creating blank entries


I have a button triggering an API workflow on a list. It takes a list in a Repeating group A (pulling from database A), and creates those things in Database B.

The problem I’m facing is that it will create the 1st 2 or 3 things in the list, then turn out completely blank things for the rest. Anyone experienced this before? It seems random as well… sometimes it works, and sometime not…

does database 1 have values for those different data fields…looks like that might be the reason
