Hi @Ryan Abbey ,
Thank you for posting query in Microsoft Q&A Platform.
It looks strange. You mentioned that in lookup or ForEach level you haven't used @item expression still getting error.
Could you please try below option and see how it goes.
If you are trying to pass @item() inside ForEach to child or Grand child. Then, kindly have @item() value set in to a variable first and then pass that variable into child or grand child of ForEach. I hope this may avoid issue. Kindly try and share updates.
Accepting answer if this helps. Please let us know if any further queries.
