Whenever we run a Cart Transform API function all the Line Item Properties are lost.
This happens as soon as the function makes a Merge operation to the cart.
This affects both Cart and Checkout where it is crucial for us to show all the Line Item Properties added by our app.
The product referenced by “parentVariantId” has some Line Item Properties, but they are lost after the Merge.
Why?Am I missing anything?
In our testing, this happens for the Expand operation as well. This is a huge blocker for us. @Nick is anybody looking into this?
We contacted Shopify Support 2 months ago about it, and they accepted it as a bug from their side, but still no fix 
They keep telling us to check out the dev changelog page often to see if it is fixed.
Hope they fix it real soon!
@Nick_Wesselman is there anybody on the Functions team who can help with this? It seems like a fairly major bug, and will prevent us from launching a new app in January if it can’t be resolved.
Hi @Nick_Wesselman - one more ping before the new year. Any update? It’s been 4 months and no word from the Function team.
Is there any work around for this issue?
From our testing, the line item properties don’t appear on the order after it’s created, so we have not been able to create any kind of workaround unfortunately.
Hey - Has anyone found a solution for this wasn’t there a recent update on cart transformation API to accommodate this? I’m unable to find that changelog now.
