I can see in the Data In field in my Zap History details that the field I need is present (purchasedItems:1)

But in the Data Out, it’s missing. Why? This is the correct data that needs to be sent.

Now what do I do? It should have been in [User Purchased Items] [1], I believe. At least that’s where it is on the Data In screen. And the field I am choosing is from a pre-built integration by the receiving product, not some random thing I built myself.
Any help would be appreciated. Thanks,
