I have a Flow looking to updated or created rows in Zoho Sheets. Then it should create an invoice in Books. No matter what I do when testing the flow I get the final error in the Books flow test showing
Zoho Books says "Invalid value passed for bulk_update"
I have even done something as simple as ROW CREATED OR UPDATED then FETCH ITEM with SEARCH BY - ITEM NAME - ${trigger.ProductService}
The Books Item Name and the ${trigger.ProductService} referenced in Sheets is exactly the same so it should find it.
I tried this with 1 row to limit the data being processed. Still the same error.
